Using Python suppose an array sorted in ascending order is rotated at some pivot unknown to you beforehand. (i.e., [0,1,2,4,5,6,7] might become [4,5,6,7,0,1,2]).
You are given a target value to search. If found in the array return its index, otherwise return “The input is not on this list”
You may assume no duplicate exists in the array.
Hint: Use a function. Use the built in method .index( ) and/or for loops.
Answer:
Explanation:
class Solution {
public int search(int[] nums, int target) {
int n = nums.length;
int low = 0 , high = n - 1;
While(low < high){//Set virtual node
int mid = (low + high) / 2;
if(nums[mid] > nums[high]){
low = mid + 1;
}else{
high = mid;
}
}
int rot = low;
low = 0;
high = n - 1;
while(low <= high){
int mid = (low + high) / 2;
Int real = (mid + rot) % n;//The virtual node is mapped to the real node.
if(nums[real] == target){
return real;
}else if(nums[real] < target){
low = mid + 1;
}else{
high = mid - 1;
}
}
return -1;
}
}

Complete the calcAverage() method that has an integer array parameter and returns the average value of the elements in the array as a double.(Java program)
Ex: If the input array is:
1 2 3 4 5
then the returned average will be:
3.0
Answer:
Explanation:
The following Java program has the method calcAverage(). It creates a sum variable which holds the sum of all the values in the array and the count variable which holds the number of elements in the array. Then it uses a For Each loop to loop through the array and go adding each element to the sum variable. Finally it calculates the average by dividing the sum by the variable count and returns the average to the user. A test case has been created in the main method using the example in the question. The output can be seen in the image attached below.
class Brainly {
public static void main(String[] args) {
int[] myArr = {1, 2, 3, 4, 5};
System.out.println(calcAverage(myArr));
}
public static double calcAverage(int[] myArr) {
double sum = 0;
double count = myArr.length;
for (int x: myArr) {
sum += x;
}
double average = sum / count;
return average;
}

Large computer programs, such as operating systems, achieve zero defects prior to release. Group of answer choices True False PreviousNext
Answer:
The answer is "False"
Explanation:
It is put to use Six Sigma had 3.4 defects per million opportunities (DPMO) from the start, allowing for a 1.5-sigma process shift. However, the definition of zero faults is a little hazy. Perhaps the area beyond 3.4 DPMO is referred to by the term "zero faults.", that's why Before being released, large computer programs, such as operating systems, must have no faults the wrong choice.
A recursive method may call other methods, including calling itself. A recursive method has:
1. a base case -- a case that returns a value or exits from a method without performing a recursive call.
2. a recursive case -- calling the method again with a smaller case..
Study the recursive method given below.
For example, this call recursiveMethod (5); returns 15:
public static int recursiveMethod (int num) (
if (num == 0)
return 1;
else {
if (numX2!=0)
return num * recursiveMethod (num -1);
else
return recursiveMethod (num-1);
}
}
1 What is the base case?
2. What does the following statement check?
3. What does the method do?
Answer:
Hence the answer is given as follows,
Explanation:
Base Case:-
If (num == 0) //This is the base case for the given recursive method
return 1;
If(num % 2!=0) checks whether num is odd.
The above condition is true for all odd numbers and false for even numbers.
if the remainder is not equal to zero when we divide the number with 2 then it is odd.
The method:-
The above recursive method calculates the product of odd numbers up to the given range(that is num)
For num=5 => 15(5*3*1).
For num=7 => 105(7*5*3*1).
For num=10 => 945(9*7*5*3*1).
A(n) _____ is a network connection device that can build tables that identify addresses on each network.
Answer:
Dynamic Router
Explanation:
A dynamic router is a network connection device that can build tables that identify addresses on each network.
What is Dynamic network?Dynamic networks are networks that vary over time; their vertices are often not binary and instead represent a probability for having a link between two nodes.
Statistical approaches or computer simulations are often necessary to explore how such networks evolve, adapt or respond to external intervention.
DNA statistical tools are generally optimized for large-scale networks and admit the analysis of multiple networks simultaneously in which, there are multiple types of nodes (multi-node) and multiple types of links (multi-plex).
Therefore, A dynamic router is a network connection device that can build tables that identify addresses on each network.

Given main(), complete the Car class (in file Car.java) with methods to set and get the purchase price of a car (setPurchasePrice(), getPurchasePrice()), and to output the car's information (printInfo()).
Ex: If the input is:
2011
18000
2018
where 2011 is the car's model year, 18000 is the purchase price, and 2018 is the current year, the output is:
Car's information:
Model year: 2011
Purchase price: 18000
Current value: 5770
Note: printInfo() should use three spaces for indentation.
Answer and Explanation:
public class Main {
int Carmodel;
int Purchaseprice;
int Currentyear;
Public void setPurchasePrice(int Purchaseprice){
this.Purchaseprice=Purchaseprice;
}
Public void getPurchasePrice(){
return Purchaseprice;
}
static void printInfo(int Carmodel int Currentyear ){
this.Carmodel=Carmodel;
this.Currentyear=Currentyear;
System.out.println(getPurchasePrice() Carmodel Currentyear);
}
}
The above java program defines a class that has three methods, a get method that returns purchase price of the object, a set method that sets purchase price of the object, and a print method that print out the information about the car object(model, year, price). The print method also takes arguments and assigns values of the arguments/parameters to the object, then prints all.

The code provided worked for the most part, it had some gramatical errors in when printing out the information as well as repeated values. I fixed and reorganized the printed information so that it is well formatted. The only thing that was missing from the code was the input validation to make sure that no negative values were passed.

SQLite is a database that comes with Android. Which statements is/are correct?
The content of an SQLite database is stored in XML formatted files because XML is the only file format supported by Android OS.
A SQLite database is just another name for a Content Provider. There is no difference as the SQLite implementation implements the Content Provider interface.
If an app creates an SQLite database and stores data in it, then all of the data in that particular database will be stored in one, single file.
A database query to an SQLite database usually returns a set of answers
To access individual entries, SQLite provides a so-called Cursor to enumerate all entries in the set.
This is yet another example of the Iterator pattern.
Answer:
1. Wrong as per my knowledge, SQLite may be an electronic database software that stores data in relations(tables).
2. Wrong. Content provider interface controls the flow of knowledge from your android application to an external data storage location. Data storage is often in any database or maybe it'll be possible to store the info in an SQLite database also.
3.Right. SQLite uses one file to store data. It also creates a rollback file to backup the stored data/logs the transactions.
4. Wrong. The queries are almost like a traditional electronic database system, the queries are going to be answered as per the conditions given and should return a group of answers or one answer depending upon the info and sort of query used.
5. Right. A cursor helps to point to one entry within the database table. this may be very helpful in manipulating the present row of the query easily.
how to Write a simple Java socket programming that a client sends a text and server receives and print.
Answer:
Java Socket programming is used for communication between the applications running on different JRE.
Java Socket programming can be connection-oriented or connection-less.
Socket and ServerSocket classes are used for connection-oriented socket programming and DatagramSocket and DatagramPacket classes are used for connection-less socket programming.
The client in socket programming must know two information:
IP Address of Server, and
Port number.
Here, we are going to make one-way client and server communication. In this application, client sends a message to the server, server reads the message and prints it. Here, two classes are being used: Socket and ServerSocket. The Socket class is used to communicate client and server. Through this class, we can read and write message. The ServerSocket class is used at server-side. The accept() method of ServerSocket class blocks the console until the client is connected. After the successful connection of client, it returns the instance of Socket at server-side.
Explanation:
Creating Client:
import java.io.*;
import java.net.*;
public class MyServer {
public static void main(String[] args){
try{
ServerSocket ss=new ServerSocket(6666);
Socket s=ss.accept();//establishes connection.
DataInputStream dis=new DataInputStream(s.getInputStream());

(c) 4
Explanation:The function strpos() is a function in php that returns the position of the first occurrence of a particular substring in a string. Positions are counted from 0. The function receives two arguments. The first argument is the string from which the occurrence is to be checked. The second argument is the substring to be checked.
In this case, the string is "Get Well Soon!" while the substring is "Well"
Starting from 0, the substring "Well" can be found to begin at position 4 of the string "Get Well Soon!".
Therefore, the function strpos("Get Well Soon!", "Well") will return 4.
Then, with the echo statement, which is used for printing, value 4 will be printed as output of the code.
Which of the following restricts the ability for individuals to reveal information present in some part of the database?
a. Access Control
b. Inference Control
c. Flow Control
d. Encyption
Answer:
it would have to be flow control which would be C.
Explanation:
Flow Control is restricts the ability for individuals to reveal information present in some part of the database. Hence, option C is correct.
What is Flow Control?The management of data flow between computers, devices, or network nodes is known as flow control. This allows the data to be processed at an effective rate. Data overflow, which occurs when a device receives too much data before it can handle it, results in data loss or retransmission.
A design concern at the data link layer is flow control. It is a method that typically monitors the correct data flow from sender to recipient. It is very important because it allows the transmitter to convey data or information at a very quick rate, which allows the receiver to receive it and process it.
The amount of data transmitted to the receiver side without any acknowledgement is dealt with by flow control.
Thus, option C is correct.

Calculate how much disk space (in sectors, tracks, and surfaces) will be required to
store 300,000 120-byte logical records if the disk is fixed sector with 512 bytes/
sector, with 96 sectors/track, 110 tracks per surface, and 8 usable surfaces. Ignore
any file header record(s) and track indexes, and assume that records cannot span
two sectors.

The amount of disk space in sectors that would be required to store 300,000 records is equal to 75,000 sectors.
Given the following data:
Number of records = 300,000.Size of each logical record = 120 byte.Number of bytes (sector) = 512.Number of sectors per track = 96.Number of tracks per surface = 110.How to calculate the required disk space?First of all, we would determine the number of logical records that can be held by each sector as follows:
Number of logical records per sector = 512/120
Number of logical records per sector = 4.3 ≈ 4.0.
Now, we can calculate the required disk space to store 300,000 records:
Disk space = 300,000/4
Disk space = 75,000 sectors.
For the tracks, we have:
Disk space in tracks = 75,000/96
Disk space in tracks = 781.25 ≈ 782.
Disk space in tracks = 782 tracks.
For the surfaces, we have:
Disk space in surfaces = 782/110
Disk space in surfaces = 7.10 ≈ 8.
Disk space in surfaces = 8 surfaces.

Gray London is a retired race car driver who helped Dale Earnhardt, Jr. get his start. He is writing a book and making a video about the early days or Dale Earnhardt. He is trying to decide whether to market these items directly over the Internet or to use intermediaries. To make this decision, he needs to know the pros and cons of each route. Provide that information and make a recommendation to him.
Answer:
Explanation:
Marketing your product directly over the internet can lead to much greater profits and there are many options that you can choose from in order to target the correct audience. Unfortunately, doing so does require marketing knowledge and is basically like growing a business. If you were to use intermediaries they already have the knowledge necessary to market your product but will take a percentage of the profits, which will ultimately limit your gains. Since Gray London is a race car driver, I am assumming that he does not have any prior technological expertise or marketing expertise, therefore I would recommend using intermediaries.
