Debugging a code involves locating the errors in a code segment, and fixing them.
How to debug the code segment?When the program was run on GDB, the program give the following error
Main.java:62: error: reached end of file while parsing
This means that we need to add a closing brace to the end of the program.
A second run after fixing this error gives another set of errors:
Main.java:4: error: class Contribution is public, should be declared in a file named Contribution.java
It should be noted that GDB only allows you to create a program with the file name Main i.e. Main.java
This means that we change the Contribution keywords in the program to Main.
After this has been done, the program gives the following output:
It took 17 contributions to reach the goal.
The maximum contribution received was $189.0.
The minimum contribution received was $3.0
The average contribution amount was $60.0.
A total of $1012.0 was collected.
So, the corrected program is:
import java.io.*;
import java.util.*;

difference between primary and secondary storage
Answer:
Primary storage also called as main memory. RAM is an example of primary memory.
Secondary storage are popular as we use them for permanent storage.
Explanation:
Primary storage are temporary such RAM which are required for your program to execute. Without these storage, we can't use the computer for any operations. These memory keeps intermediate data and garbage out when the data no longer required.
On the other hand, when we need to store the data for future reference such as files, photos and videos we use secondary storage devices such as usb drive, hard disk etc.
Consider the following language:
L={ |M is a Turing Machine and M accepts at least one palindrome,
and rejects at least one palindrome}
a. Is L a decidable language? Prove your answer.
b. Is L a recognizable language? Prove your answer.
L is a decidable language because the Turing machine accepts it.
L is a recognizable language if TM M recognizes it.
How do you know if a language is decidable?A language is said to be decidable only when there seems to exists a Turing machine that is said to accepts it,
Here, it tends to halts on all inputs, and then it answers "Yes" on words that is seen in the language and says "No" on words that are not found in the language. The same scenario applies to recognizable language.
So, L is a decidable language because the Turing machine accepts it.
L is a recognizable language if TM M recognizes it.

Write a program whose inputs are two integers, and whose output is the smallest of the two values.
Ex: If the input is:
7
15
the output is:
7
Preferred in Python
Method 1 :
Using If else statements: If the condition checks whether num1 is smaller than num2 if so it will print 'Smallest of these two integers is num1'.
else it will print 'Smallest of these two integers is num2'
Method 2:
Using the 'min' method: using the method min(num1,num2), the program finds the smallest value and prints it directly to the user.
Python Program using method 1
#PYTHON PROGRAM TO FIND SMALLEST INTEGER VALUE FROM TWO INPUTS FROM USER - Method 1
#Accepts inputs from user
num1 = int (input ("Enter your first number:")) #Gets the first integer input from user and stores in num1
num2 = int (input ("Enter your second number: ")) #Gets the second integer input from user and stores in num2
#Finding output by if else
#Checks num1 smaller than num2
if (num1 < num2):
#assign num1 to small
small = num1
else:

For instance; an input of 4.75 feet should become 4 feet and 9 inches.
The program to illustrate the conversion of the height is illustrated below.
How to illustrate the program?The information here is to convert 1 inch = 2.54 cm. First, we will take user input of height in cm. We first convert this to inches by dividing by 2.54
After that, we use Floor Division // and Modulo % by 12 to get feet and inches respectively.
The inches will be in a lot of decimals. We round this off to 2 decimal places and finally print out the converted height.
The code will be:
# Take user input for height in cm
height_cm = float(input("Enter your height in cm: "))
# Convert height to inches
height_in = height_cm / 2.54
# Get feet by taking floor division with 12
feet = height_in // 12
# Get inches by taking modulo division with 12
inches = height_in % 12

Choose the output result of the below code.
Answer:
B
Explanation:
When you initialize an instance of FunEvent(tags, year) and assign it to bc. The instance variables in this case are: self.tags = ["g", "ml"] and self.year = 2022. But then you alter tags, which will also change self.tags, since self.tags is a reference to the list you passed in as an argument. This is not the case when you do year=2023 because, first of all, integers are not mutable, and also because even if somehow integers were mutable, you're not changing the object in-place, you're simply changing the where the "variable" is pointing to. So for example if you did tags = ["g", "ml", "bc"] instead of tags.append("bc"), it would also not change the value of the instance variable "tags", because you wouldn't be changing the object in-place. So when you print(bc), the instance variables will be ["g", "ml", "bc"] and 2022. When you try to print an object, it call try to convert it into a string using the __str__ magic method. In this case it will return a string formatted as "Event(tags={self.tags}, year={self.year}) which will output "Event(tags=['g', 'ml', 'bc'], year=2022)" So the correct answer is B

Explanation: I think this would work for you. I leace comments in the answer.
The program that reads a list of integers into a list as long as the integers are greater than zero is coded in the source code.
Source code:
user_numbers = []
user_input = int(input("Enter an integer (enter a non-positive integer to stop): "))
while user_input > 0:
user_numbers.append(user_input)
user_input = int(input("Enter an integer (enter a non-positive integer to stop): "))
print(user_numbers)
In this program, we initialize an empty list user_numbers to store the integers entered by the user. We then use a while loop to repeatedly prompt the user to enter an integer.
If the entered integer is greater than 0, it is appended to the user_numbers list. If the entered integer is non-positive (less than or equal to 0), the loop terminates.
