Palindrome reads the same from left or right, mom for example. There is a palindrome which must be modified, if possible. Change exactly one character of the string to another character in the range ascii[a-z] so that the string meets the following three conditions:
a. The new string is lower alphabetically than the initial string.
b. The new string is the lowest value string alphabetically that can be created from the original palindrome after making only one change.
c. The new string is not a palindrome.
Return the new string, or, if it not possible to create a string meeting the criteria, return the string IMPOSSIBLE.
Example:
palindromeStr = 'aaabbaaa'
O Possible strings lower alphabetically than 'aaabbaaa' after one change are [aaaabaaa', 'aaabaaaa').
O aaaabaaa' is not a palindrome and is the lowest string that can be created from palindromeStr.
Answer:
See explaination
Explanation:
public class PalindromeChange {
public static void main(String[] args) {
System.out.println("mom to non palindrom word is: "+changTONonPalindrom("mom"));
System.out.println("mom to non palindrom word is: "+changTONonPalindrom("aaabbaaa"));
}

int mid=str.length()/2;
boolean found=false;
char character=' ';

{
for(i=mid+1;i<str.length();i++)
{
character = str.charAt(i);
if(character!='a')
{

// This gives the character 'a'
int ascii = (int) character;
ascii-=1;
str = str.substring(0, i) + (char)ascii+ str.substring(i + 1);

An attacker compromises the Washington Post's web server and proceeds to modify the homepage slightly by inserting a 1x1 pixel iframe that directs all website visitors to a webpage of his choosing that then installs malware on the visitors' computers. The attacker did this explicitly because he knows that US policymakers frequent the website. This would be an example of a ___________ attack.
Answer:
Water holing is the correct answer to this question.
Explanation:
Waterholing:-
It is a kind of attack in which the attacker detects the sites that the targets of the group frequently access and then afflicts the sites with the ransomware. Which afflicts selected representatives of the target group.
The watering hole assault is a data breach wherein the individual attempts to infiltrate a particular demographic of end-users by harming sites reported to be visited by team members. The aim is to compromise a specific target data and gain network access at the perpetrator's place of work.
Implement the function pairSum that takes as parameters a list of distinct integers and a target value n and prints the indices of all pairs of values in the list that sum up to n. If there are no pairs that sum up to n, the function should not print anything. Note that the function does not duplicate pairs of indices
Answer:
Following are the code to this question:
def pairSum(a,x): #find size of list
s=len(a) # use length function to calculte length of list and store in s variable
for x1 in range(0, s): #outer loop to count all list value
for x2 in range(x1+1, s): #inner loop
if a[x1] + a[x2] == x: #condition check
print(x1," ",x2) #print value of loop x1 and x2
pairSum([12,7,8,6,1,13],13) #calling pairSum method
Output:
0 4
1 3
Explanation:
Description of the above python can be described as follows:
In the above code, a method pairSum is declared, which accepts two-parameter, which is "a and x". Inside the method "s" variable is declared that uses the "len" method, which stores the length of "a" in the "s" variable. In the next line, two for loop is declared, in the first loop, it counts all variable position, inside the loop another loop is used that calculates the next value and inside a condition is defined, that matches list and x variable value. if the condition is true it will print loop value.A user has called the company help desk to inform them that their Wi-Fi enabled mobile device has been stolen.

(JAVA programming) Guess Number program
Program description: Write a program named GuessNumber that plays a game in which the program picks a secret number and the user tries to guess it.
1) The program first asks the user to enter the maximum value for the secret number.
2) Next, it chooses a random number that is >= 1 and<= the maximum number.
3) Then the user must try to guess the number.
4) When the user succeeds, the program asks the user whether or not to play another game.
The following example shows what the user will see on the screen (user input is in bold):
2. Input and output Guess the secret number.
Enter maximum value for secret number: 10
A new secret number has been chosen.
Enter guess: 3
Too low; try again. Enter guess: 8
Too low; try again. Enter guess: 9
Too low; try again. Enter guess: 10
You won in 4 guesses!
Play again? (Y/N) y
A new secret number has been chosen.
Enter guess: 7
Too high; try again.
Enter guess: 3
Too low; try again.
Enter guess: 5
You won in 3 guesses!
Play again? (Y/N) n
The user may enter any number of spaces before and after each input. The program should terminate if the user enters any input other than y or Y when asked whether to play again. Hints 1) Use two while statement (nested) for the whole program.
2) Use the following statement to pick the secret number: int secretNumber = (int) (Math.random() * maxNumber) + 1; 3) Use trim() method to trim any number of spaces in an input. 4) Use the equalsIgnoreCase method to test whether the user entered y or Y.
Answer:
The following are the program in the Java Programming Language.
import java.util.Random; //import package
import java.util.Scanner; //import package
//define a class
public class GuessNumber {
//define a main method
public static void main(String[] args)
{
//create object of the Scanner class
Scanner cs = new Scanner(System.in);
//print message
System.out.println("Guess the secret number\n");
//print message
System.out.print("Enter the maximum value for the secret number: ");
//get input in the integer variable through scanner class object
int maxNum=cs.nextInt();
//create object of the Random class
Random ran = new Random();
//declare an integer variable that store random number
int guessed = 1+ran.nextInt(maxNum);
//set the while loop
while (true)
{
//print message
System.out.println("\nA new secret number has been chosen.");
//set two integer variables to 0
int user = 0;
int count = 0;
//set the while loop
while (user != guessed)
{
//print message
System.out.print("Enter guess: ");
//get input in the variable from user
user = cs.nextInt();
//increment the variable by 1
count++;
//check that the user is less than guessed
if (user < guessed)
{
//then, print message
System.out.println("low, try again.");
}
//check that user is greater than guessed
else if (user > guessed)
{
//then, print message
System.out.println("high, try again");
}
}
//print message with count
System.out.println("You won in " + count + "!");
//print message and get input
System.out.print("\nPlay again? (Y/N)");
cs.nextLine();
String again = cs.nextLine();
//check that input is y
if(again.equalsIgnoreCase("y"))
{
//then, loop again iterates
continue;
}
//otherwise, loop is break
else{
break;
}
}
}
}
Explanation:
The following are the description of the program :
Firstly, we import the required packages and define the class 'GuessNumber'. Inside the class, we create the object of the scanner class and the random class then, get input from the user through scanner class object and generate random number through the random class object. Then, set the while infinite loop in which we declare two integer data type variables and assign them to 0 then, set while loop inside the infinite loop that iterates when the 1st variable is not equal to the second one then, get input from the user through scanner class object. Then, check that input number is less than the random number then, print message otherwise, again check that input number is greater than the random number then, print message or if both numbers are equal then print the message with the count. Finally, the program asks for play again, if the input is 'y' then, infinite loop again iterates otherwise the infinite loop is break.The java program to compile the numbers gotten from the user request is:
import java.util.Scanner; //import packagepublic class GuessNumber { public static void main(String[] args) { Scanner cs = new Scanner(System.in); System.out.println("Guess the secret number\n"); System.out.print("Enter the maximum value for the secret number: "); int maxNum=cs.nextInt(); Random ran = new Random(); //declare an integer variable that store random number int guessed = 1+ran.nextInt(maxNum); //set the while loop while (true) { //print message System.out.println("\nA new secret number has been chosen."); //set two integer variables to 0 int user = 0; int count = 0; //set the while loop while (user != guessed) { //print message System.out.print("Enter guess: "); //get input in the variable from user user = cs.nextInt(); //increment the variable by 1 count++; //check that the user is less than guessed if (user < guessed) { //then, print message System.out.println("low, try again."); } //check that user is greater than guessed else if (user > guessed) { //then, print message System.out.println("high, try again"); } } //print message with coun System.out.println("You won in " + count + "!"); //print message and get input System.out.print("\nPlay again? (Y/N)"); cs.nextLine(); String again = cs.nextLine(); //check that input is y if(again.equalsIgnoreCase("y")) { //then, loop again iterates continue; } //otherwise, loop is break else{ break; } } }}Read more about java programming here:

This represents a group of Book values as a list (named books). We can then dig through this list for useful information and calculations by calling the methods we're going to implement. class Library: Define the Library class. • def __init__(self): Library constructor. Create the only instance variable, a list named books, and initialize it to an empty list. This means that we can only create an empty Library and then add items to it later on.
Answer:
class Library: def __init__(self): self.books = [] lib1 = Library()lib1.books.append("Biology") lib1.books.append("Python Programming Cookbook")Explanation:
The solution code is written in Python 3.
Firstly, we can create a Library class with one constructor (Line 2). This constructor won't take any input parameter value. There is only one instance variable, books, in the class (Line 3). This instance variable is an empty list.
To test our class, we can create an object lib1 (Line 5). Next use that object to add the book item to the books list in the object (Line 6-8).
Suppose you are given a text file. Design a Python3 program to encrypt/decrypt that text file as follows:
If the character is an upper case character then shift that character forward, s characters forward in the alphabet.
If the character is a lower case character then shift that character backwards, s characters backwards in the alphabet.
If the character is a numeric character then shift that character also backwards, s characters backwards in the 1-digit numbers set {0,1,2,3,4,5,6,7,8,9}.
You must design two functions; one to encrypt. The other one is to decrypt. All white space and punctuation marks must be ignored(cannot be changed). If you reach Z, or A, the shifting may continue as a cycle(A comes after Z, Z comes before A). Both files (original text file and the encrypted text file) must be stored in the working directory of Python.

}
Explanation:
Given above is the equivalent code using Switch case in JavaThe switch case test multiple levels of conditions and can easily replace the uses of several if....elseif.....else statements.When using a switch, each condition is treated as a separate case followed by a full colon and the the statement to execute if the case is true.The default statement handles the final else when all the other coditions are falseDefine a function CoordTransform() that transforms the function's first two input parameters xVal and yVal into two output parameters xValNew and yValNew. The function returns void. The transformation is new = (old + 1) * 2. Ex: If xVal = 3 and yVal = 4, then xValNew is 8 and yValNew is 10.

Write the method addItemToStock to add an item into the grocery stock array. The method will: • Insert the item with itemName add quantity items to stock. • If itemName is already present in stock, increase the quantity of the item, otherwise add new itemName to stock. • If itemName is not present in stock, insert at the first null position in the stock array. After the insertion all items are adjacent in the array (no null positions between two items). • Additionally, double the capacity of the stock array if itemName is a new item to be inserted and the stock is full.
Answer:
#include <stdio.h>
#include <iostream>
using namespace std;
int main()
{
//varible to indicate size of the array
int size=20;
//arrays to hold grocery item names and their quantities
std::string grocery_item[size];

Explanation:
1. The length of the array and the level of full stock has been defined inside the program.
2. Program can be tested for varying values of length of array and full stock level.
3. The variables are declared outside the do-while loop.
4. Inside do-while loop, user input is taken. The loop runs until user opts to quit the program.
5. Inside do-while loop, the logic for adding the item to the array and adding the quantity to the stock has been included. For loops have been used for arrays.
6. The program only takes user input for the item and the respective quantity to be added.

Define a thread that will use a TCP connection socket to serve a client Behavior of the thread: it will receive a string from the client and convert it to an uppercase string; the thread should exit after it finishes serving all the requests of a client Create a listening TCP socket While (true) { Wait for the connection from a client Create a new thread that will use the newly created TCP connection socket to serve the client Start the new thread. }
Answer:
The primary intention of writing this article is to give you an overview of how we can entertain multiple client requests to a server in parallel. For example, you are going to create a TCP/IP server which can receive multiple client requests at the same time and entertain each client request in parallel so that no client will have to wait for server time. Normally, you will get lots of examples of TCP/IP servers and client examples online which are not capable of processing multiple client requests in parallel.

Given the following header: vector split(string target, string delimiter); implement the function split so that it returns a vector of the strings in target that are separated by the string delimiter. For example: split("10,20,30", ",") should return a vector with the strings "10", "20", and "30". Similarly, split("do re mi fa so la ti do", " ") should return a vector with the strings "do", "re","mi", "fa", "so", "la", "ti", and "do". Write a program that inputs two strings and calls your function to split the first target string by the second delimiter string and prints the resulting vector all on line line with elements separated by commas.

5.14 ◆ Write a version of the inner product procedure described in Problem 5.13 that uses 6 × 1 loop unrolling. For x86-64, our measurements of the unrolled version give a CPE of 1.07 for integer data but still 3.01 for both floating-point data. A. Explain why any (scalar) version of an inner product procedure running on an Intel Core i7 Haswell processor cannot achieve a CPE less than 1.00. B. Explain why the performance for floating-point data did not improve with loop unrolling.
Answer:
(a) the number of times the value is performs is up to four cycles. and as such the integer i is executed up to 5 times. (b)The point version of the floating point can have CPE of 3.00, even when the multiplication operation required is either 4 or 5 clock.
Explanation:
Solution
The two floating point versions can have CPEs of 3.00, even though the multiplication operation demands either 4 or 5 clock cycles by the latency suggests the total number of clock cycles needed to work the actual operation, while issues time to specify the minimum number of cycles between operations.
Now,
sum = sum + udata[i] * vdata[i]
in this case, the value of i performs from 0 to 3.
Thus,
The value of sum is denoted as,
sum = ((((sum + udata[0] * vdata[0])+(udata[1] * vdata[1]))+( udata[2] * vdata[2]))+(udata[3] * vdata[3]))
Thus,
(A)The number of times the value is executed is up to 4 cycle. And the integer i performed up to 5 times.
Thus,
(B) The floating point version can have CPE of 3.00, even though the multiplication operation required either 4 or 5 clock.
Let A be an array of n numbers. Recall that a pair of indices i, j is said to be under an inversion if A[i] > A[j] and i < j. Design a divide-and-conquer based algorithm to count the number of inversions in an array of n numbers. You can start by splitting into two subproblems. Answer clearly how you do the merge step, then obtain a recurrence relation that captures the run time of the algorithm. Solve the recurrence relation. Write the complete pseudocode.

Explanation:
3.15 LAB: Countdown until matching digits
Write a program that takes in an integer in the range 20-98 as input. The output is a countdown starting from the integer, and stopping when both output digits are identical.
Ex: If the input is:
93
the output is:
93 92 91 90 89 88
Ex: If the input is:
77
the output is:
77
Ex: If the input is:
15
or any value not between 20 and 98 (inclusive), the output is:
Input must be 20-98.
#include
using namespace std;
int main() {
// variable
int num;
// read number
cin >> num;
while(num<20||num>98)
{
cout<<"Input must be 20-98 ";
cin>> num;
}
while(num % 10 != num /10)
{
// print numbers.
cout<
// update num.
num--;
}
// display the number.
cout<
return 0;
}
I keep getting Program generated too much output.
Output restricted to 50000 characters.
Check program for any unterminated loops generating output
Answer:
See explaination
Explanation:
n = int(input())
if 20 <= n <= 98:
while n % 11 != 0: // for all numbers in range (20-98) all the identical
digit numbers are divisible by 11,So all numbers that
are not divisible by 11 are a part of count down, This
while loop stops when output digits get identical.
print(n, end=" ")
n = n - 1
print(n)
else:
print("Input must be 20-98")
Fill in the blanks to make the factorial function return the factorial of n. Then, print the first 10 factorials (from 0 to 9) with the corresponding number. Remember that the factorial of a number is defined as the product of an integer and all integers before it. For example, the factorial of five (5!) is equal to 1*2*3*4*5
Answer:
Following are code of factorial in python language
def factorial(n): # function
result=1 #variable
for x in range(2,n+1): #iterating the loop
result=result*x #storing result
return result #return result
for n in range(10): #iterating loop
print(n,factorial(n)) #print factorial
Output:
Following are the attachment of output
Explanation:
Missing information :
In the question the information is missing the code is missing which we have to correct it following are the code that are mention below.
def factorial(n): # function
result=1 #variable
for x in range( ): #iterating the loop
result= #storing result
return #return result
for n in range( ): #iterating loop
print(n,factorial(n)) #print factorial
Following are the description of code
We have create a function factorial in this we have pass the one parameter i.e "n".In the for loop we have pass 2,n+1 which has been used to iterating the loop calculating factorial and string the result in the result variable In the main function we have pass the range on which we have to calculated the factorialFinally the print function will print the factorial .Following are the attachment snip of code in the python language
By filling in the blanks to make the factorial function return the factorial of n, we have the following.
def factorial (n):
result = 1
for x in range(2, n+1):
result = result*x
return result
for n in range(10):
print(n,factorial(n))
The math module in Python includes a number series of mathematical operations that may be easily done using the module. The math . factorial() function computes the factorial of a given number.
To write the code perfectly and fill in the blanks:
We created a math factorial function with n parameterThis code is being passed through the iterating loop 2,n+1 for calculation. We string the result, perform the range, and print out the result using the print formula.CODE:
def factorial (n):
result=1
for x in range(2, n+1):
result = result*x
return result
for n in range(10):
print(n,factorial(n))
RESULT:
0 1
1 1
2 2
3 6
4 24
5 120
6 720
7 5040
8 40320
9 362880
Therefore, we can conclude that we've understood how to write the factorial function code in python.

Which of the following is a component of slides
g Q 2 Suppose I need a data structure having the following characteristics: a) must be very space efficient, and b) I have a good idea of how much total data needs to be stored. b) must have fastest access possible, and c) once I add an item to the data structure, I do not remove it. Part 1: What data structure would I choose and why? (2,4) Part 2: If I remove characteristic b, what similar data structure is a possible candidate?
Explanation:
a.I would choose an advanced data structure like dispersion tables.
Scatter tables, better known as hash tables, are one of the most frequently used data structures. To get an initial idea, scatter tables make it possible to have a structure that relates a key to a value, such as a dictionary. Internally, the scatter tables are an array. Each of the array positions can contain none, one or more dictionary entries.
It will normally contain a maximum of one, which allows quick access to the elements, avoiding a search in most cases. To know at which position in the array to search or insert a key, a scatter function is used. A scatter function relates each key to an integer value. Two equal keys must have the same dispersion value, also called a hash value, but two different keys can have the same dispersion value, which would cause a collision.
B. If I eliminated the characteristic b, a possible candidate keeping the previous characteristics would be: Balanced binary trees
Balanced binary trees are data structures that store key-data pairs, in an orderly way according to the keys, and allow quick access to the data, given a particular key, and to go through all the elements in order.
They are appropriate for large amounts of information and have less overhead than a scatter table, although the access time is of greater computational complexity.
Although the storage form has a tree structure internally, this is not externalized in the API, making the handling of the data transparent. They are called balanced because, each time they are modified, the branches are rebalanced in such a way that the height of the tree is as low as possible, thus shortening the average time of access to the data.
Write a static method named contains that accepts two arrays of integers a1 and a2 as
parameters and that returns a boolean value indicating whether or not a2's sequence of
elements appears in a1 (true for yes, false for no). The sequence of elements in a2 may
appear anywhere in a1 but must appear consecutively and in the same order. For example, if
variables called list1 and list2 store the following values:
int[] list1 = {1, 6, 2, 1, 4, 1, 2, 1, 8};
int[] list2 = {1, 2, 1};
Then the call of contains(list1, list2) should return true because list2's sequence of
values {1, 2, 1} is contained in list1 starting at index 5. If list2 had stored the values {2,
1, 2}, the call of contains(list1, list2) would return false because list1 does not
contain that sequence of values. Any two lists with identical elements are considered to contain
each other, so a call such as contains(list1, list1) should return true.

SUMMING THE TRIPLES OF THE EVEN INTEGERS FROM 2 THROUGH 10) Starting with a list containing 1 through 10, use filter, map and sum to calculate the total of the triples of the even integers from 2 through 10. Reimplement your code with list comprehensions rather than filter and map.
Answer:
numbers=list(range(1,11)) #creating the list
even_numbers=list(filter(lambda x: x%2==0, numbers)) #filtering out the even numbers using filter()
triples=list(map(lambda x:x*3 ,even_numbers)) #calculating the triples of each even number using map
total_triples=sum(triples) #calculatting the sum
numbers=list(range(1,11)) #creating the list
even_numbers=[x for x in numbers if x%2==0] #filtering out the even numbers using list comprehension
triples=[x*3 for x in even_numbers] #calculating the triples of each even number using list comprehension
total_triples=sum(triples) #calculating the sum.
