Which of the following best describes the existence of undecidable problems?
Answer:
D.
Explanation:
Its the exact definition of an undecidable problem. Plus I have my notebook open next to me and that's what it says, trust bro.
An undecidable problem is a problem for which no algorithm can be constructed that always produces a correct output. The correct option is D.
What is undecidable problem?Problems that cannot be solved by an algorithm are known as undecidable problems since no computer program can come up with a solution that works for every scenario.
This is a key drawback of computing systems, and it has been analytically shown that some issues are intractable from the start.
Decision issues that lack an algorithmic solution are referred to as undecidable.
A issue that cannot be solved by a computer or computer software of any type has never been solved by a computer. There is no such thing as a Turing machine that can solve an insoluble problem.
Thus, the correct option is D.

We have looked at several basic design tools, such as hierarchy charts, flowcharts, and pseudocode. Each of these tools provide a different view of the design as they work together to define the program. Explain the unique role that each design tool provides (concepts and/or information) to the design of the program.
Answer:
Answered below
Explanation:
Pseudocode is a language that program designers use to write the logic of the program or algorithms, which can later be implemented using any programming language of choice. It helps programmers focus on the logic of the program and not syntax.
Flowcharts are used to represent the flow of an algorithm, diagrammatically. It shows the sequence and steps an algorithm takes.
Hierarchy charts give a bird-eye view of the components of a program, from its modules, to classes to methods etc.

A perpetual system of inventory can be defined as a method of financial accounting, which involves the updating informations about an inventory on a continuous basis (in real-time) as the sales or purchases are being made by the customers, through the use of enterprise management software applications and a digitized point-of-sale (POS) equipment.
Under a perpetual system of inventory, updates of the journal entry for cost of goods sold or received would include debiting accounts receivable and crediting sales immediately as it is being made or happening.
Hence, an advantage of the perpetual system of inventory over the periodic system of inventory is that, it ensures the inventory account balance is always accurate provided there are no spoilage, theft etc.
The following are the characteristic of a perpetual inventory system;
I. It is the most popular choice for modern business.
II. Inventory is updated in near real-time.
III. It provides up-to-date balance information and requires fewer physical counts.
Consider the following code segment. int[][] arr = {{3, 2, 1}, {4, 3, 5}}; for (int row = 0; row < arr.length; row++) { for (int col = 0; col < arr[row].length; col++) { if (col > 0) { if (arr[row][col] >= arr[row][col - 1]) { System.out.println("Condition one"); } } if (arr[row][col] % 2 == 0) { System.out.println("Condition two"); } } } As a result of executing the code segment, how many times are "Condition one" and "Condition two" printed?
Answer:
Condition one - 1 time
Condition two - 2 times
Explanation:
Given
The above code segment
Required
Determine the number of times each print statement is executed
For condition one:
The if condition required to print the statement is: if (arr[row][col] >= arr[row][col - 1])
For the given data array, this condition is true only once, when
[tex]row = 1[/tex] and [tex]col = 2[/tex]
i.e.
if(arr[row][col] >= arr[row][col - 1])
=> arr[1][2] >= arr[1][2 - 1]
=> arr[1][2] >= arr[1][1]
=> 5 >= 3 ---- True
The statement is false for other elements of the array
Hence, Condition one is printed once
For condition two:
The if condition required to print the statement is: if (arr[row][col] % 2 == 0)
The condition checks if the array element is divisible by 2.
For the given data array, this condition is true only two times, when
[tex]row = 0[/tex] and [tex]col = 1[/tex]
[tex]row = 1[/tex] and [tex]col = 0[/tex]
i.e.
if (arr[row][col] % 2 == 0)
When [tex]row = 0[/tex] and [tex]col = 1[/tex]
=>arr[0][1] % 2 == 0
=>2 % 2 == 0 --- True
When [tex]row = 1[/tex] and [tex]col = 0[/tex]
=>arr[1][0] % 2 == 0
=> 4 % 2 == 0 --- True
The statement is false for other elements of the array
Hence, Condition two is printed twice
In the following code segment, assume that the ArrayList numList has been properly declared and initialized to contain the Integer values [1, 2, 2, 3]. The code segment is intended to insert the Integer value val in numList so that numList will remain in ascending order. The code segment does not work as intended in all cases.
int index = 0;
while (val > numList.get(index))
{
index++;
}
numList.add(index, val);
For which of the following values of val will the code segment not work as intended?
a. 0
b. 1
c. 2
d. 3
e. 4
Answer:
e. 4
Explanation:
The code segment will not work as intended if the value of the variable val is 4. This is because the while loop is comparing the value of the variable val to the value of each element within the numList. Since there is no element that is bigger than or equal to the number 4, this means that if the variable val is given the value of 4 it will become an infinite loop. This would cause the program to crash and not work as intended.
The program illustrates the use of while loops.
The code segment will not work as intended when the value of val is 4
LoopsLoops are used to perform repeated operations
The programFrom the program, the while loop is repeated under the following condition:
val > numList.get(index)
This means that:
The loop is repeated as long as val has a value greater than the index of numList (i.e. 3)
From the list of options, 4 is greater than 3.
Hence, the code segment will not work as intended when the value of val is 4

The first and second numbers in the Fibonacci sequence are both 1. After that, each subsequent number is the sum of the two preceding numbers. The first several numbers in the sequence are: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, etc. Write a function named fib that takes a positive integer parameter and returns the number at that position of the Fibonacci sequence. For example fib(1)
Answer:
In Python:
def fib(nterms):
n1, n2 = 1, 1
count = 0
while count < nterms:
term = n1
nth = n1 + n2
n1 = n2
n2 = nth
count += 1
return term
Explanation:
This line defines the function
def fib(nterms):
This line initializes the first and second terms to 1
n1, n2 = 1, 1
This line initializes the Fibonacci count to 0
count = 0
The following while loops gets the number at the position of nterms
while count < nterms:
term = n1
nth = n1 + n2
n1 = n2
n2 = nth
count += 1
This returns the Fibonnaci term
return term
Consider the following incomplete method, which is intended to return the longest string in the string array words. Assume that the array contains at least one element.
public static String longestWord(String[] words)
{
/* missing declaration and initialization */
for (int k = 1; k < words.length; k++)
{
if (words[k].length() > longest.length())
{
longest = words[k];
}
}
return longest;
}
Which of the following can replace /* missing declaration and initialization */ so that the method will work as intended?
a. int longest = 0;
b. int longest = words[0].length();
c. String longest = "";
d. String longest = words[0];
e. String longest = words[1];
Answer:
String longest = "";
Explanation:
The initialization that would allow the method to work as intended would be the following
String longest = "";
This is because the method is looping through the array provided as an argument and comparing each word in the array with the word saved inside the variable called longest. The length of both are compared and if the word in the array is longer than the string saved in the variable longest then it is overwritten with the word in the array.

Answer:
In Python:
#1
service = input("Enter desired auto service: ")
print("You entered: "+service)
#2
if service.lower() == "oil change":
print("Cost of oil change: $35")
elif service.lower() == "car wash":
print("Cost of car wash: $7")
elif service.lower() == "tire rotation":
print("Cost of tire rotation: $19")
else:
print("Invalid Service")
Explanation:
First, we prompt the user for the auto service
service = input("Enter desired auto service: ")
Next, we print the service entered
print("You entered: "+service)
Next, we check if the service entered is available (irrespective of the sentence case used for input). If yes, the cost of the service is printed.
This is achieved using the following if conditions
For Oil Change
if service.lower() == "oil change":
print("Cost of oil change: $35")
For Car wash
elif service.lower() == "car wash":
print("Cost of car wash: $7")
For Tire rotation
elif service.lower() == "tire rotation":
print("Cost of tire rotation: $19")
Any service different from the above three, is invalid
else:
print("Invalid Service")

You've created a new programming language, and now you've decided to add hashmap support to it. Actually you are quite disappointed that in common programming languages it's impossible to add a number to all hashmap keys, or all its values. So you've decided to take matters into your own hands and implement your own hashmap in your new language that has the following operations:
insert x y - insert an object with key x and value y.
get x - return the value of an object with key x.
addToKey x - add x to all keys in map.
addToValue y - add y to all values in map.
To test out your new hashmap, you have a list of queries in the form of two arrays: queryTypes contains the names of the methods to be called (eg: insert, get, etc), and queries contains the arguments for those methods (the x and y values).
Your task is to implement this hashmap, apply the given queries, and to find the sum of all the results for get operations.
Example
For queryType = ["insert", "insert", "addToValue", "addToKey", "get"] and query = [[1, 2], [2, 3], [2], [1], [3]], the output should be hashMap(queryType, query) = 5.
The hashmap looks like this after each query:
1 query: {1: 2}
2 query: {1: 2, 2: 3}
3 query: {1: 4, 2: 5}
4 query: {2: 4, 3: 5}
5 query: answer is 5
The result of the last get query for 3 is 5 in the resulting hashmap.
For queryType = ["insert", "addToValue", "get", "insert", "addToKey", "addToValue", "get"] and query = [[1, 2], [2], [1], [2, 3], [1], [-1], [3]], the output should be hashMap(queryType, query) = 6.
The hashmap looks like this after each query:
1 query: {1: 2}
2 query: {1: 4}
3 query: answer is 4
4 query: {1: 4, 2: 3}
5 query: {2: 4, 3: 3}
6 query: {2: 3, 3: 2}
7 query: answer is 2
The sum of the results for all the get queries is equal to 4 + 2 = 6.

developed the first compiler and conducted work that led to the development of COBOL ?
Answer:
Grace Hopper.
Explanation:
Grace Hopper was a US Naval Rear Admiral and an American computer scientist who was born on the 9th of December, 1906 in New York city, United States of America. She worked on the first commercial computer known as universal automatic computer (UNIVAC), after the second World War II.
In 1953 at the Remington Rand, Grace Hopper invented the first high-level programming language for UNIVAC 1 by using words and expressions.
Additionally, the high-level programming language known as FLOW-MATIC that she invented in 1953 paved the way for the development of common business-oriented language (COBOL).
Hence, Grace Hopper developed the first compiler and conducted work that led to the development of COBOL.
Write a program that will perform a few different String operations. The program must prompt for a name, and then tell the user how many letters are in the name, what the first letter of the name is, and what the last letter of the name is. It should then end with a goodbye message. A sample transcript of what your program should do is below:
Enter your name: Jeremy
Hello Jeremy!
Your name is 6 letters long.
Your name starts with a J.
Your name ends with a y.
Goodbye!
Answer:
Follows are the code to this question:
import java.util.*;//import package for user input
public class Main//defining a class Main
{
public static void main(String[] asp)//main method
{
String n;//defining String variable
Scanner oxr=new Scanner(System.in);//creating Scanner class Object
System.out.print("Enter your name: ");//print message
n=oxr.next();//input value
System.out.println("Hello "+n+"!");//print message with value
System.out.println("Your name is "+n.length()+" letters long.");//print message with value
System.out.println("Your name starts with a "+n.charAt(0)+".");//print message with value
System.out.println("Your name ends with a "+n.charAt(n.length()-1)+".");//print message with value
System.out.print("Goodbye!");//print message
}
}
Output:
Please find the attached file.
Explanation:
In the above-given code, A string variable "n" is declared, that uses the Scanner class object for input the value from the user-end.
In the next step, the multiple print method has used, which calculates the length, first and the last latter of the string value, and uses the print method to print the calculated value with the given message.
Given that the variable named Boy = "Joey" and the variable named Age = 6, create statements that will output the following message:
Congratulations, Joey! Today you are 6 years old.
First, write one statement that will use a variable named Message to store the message. (You will need to concatenate all of the strings and variables together into the one variable named Message. If you don't know what that means, read the section in Chapter 1 about concatenation.)
Then write a second statement that will simply output the Message variable.
