Program to Find the Sum of Integers from A to B

Here is a program in Python that calculates the sum of integers from A to B:

def find_sum(A, B):
    if A > B:
        return 0
    else:
        return sum(range(A, B+1))

A = int(input("Enter the starting number (A): "))
B = int(input("Enter the ending number (B): "))

result = find_sum(A, B)
print("The sum of integers from", A, "to", B, "is:", result)

To use this program, you need to input the starting number (A) and the ending number (B). The program will then calculate the sum of all the integers from A to B, inclusive.

Let's break down the program:

1. The `find_sum` function takes two parameters, A and B. It first checks if A is greater than B. If it is, it means that the range is invalid, and the function returns 0. Otherwise, it uses the `sum` function to calculate the sum of all the integers in the range from A to B (inclusive).

2. The program prompts the user to enter the starting number (A) and the ending number (B) using the `input` function and converts them to integers using the `int` function.

3. The program calls the `find_sum` function with the inputted values of A and B and stores the result in the `result` variable.

4. Finally, the program prints the result, displaying the sum of integers from A to B.

Please note that this program assumes that A and B are both integers and that A is less than or equal to B. If you input non-integer values or A is greater than B, the program will return 0 as the sum.

I hope this helps! Let me know if you have any further questions.
