Sum of Last Digits

Write a Python program that takes three integers and checks whether the sum of the last digit of the first number and the last digit of the second number equals the last digit of the third number.

Sample Solution:

Python Code:

# Define a function named check_last_digit that checks if the last digits of the sum of x and z are equal to the last digit of y.
def check_last_digit(x, y, z):
    # Convert the sum of x and z to a string, extract the last digit, and compare it with the last digit of y.
    return str(x + z)[-1] == str(y)[-1]

# Test the function with different values for x, y, and z and print the results.

# Test case 1
print(check_last_digit(12, 26, 44))

# Test case 2
print(check_last_digit(145, 122, 1010))

# Test case 3
print(check_last_digit(0, 20, 40))

# Test case 4
print(check_last_digit(1, 22, 40))

# Test case 5
print(check_last_digit(145, 129, 104))

Sample Output:

True
False
True
False
True

Explanation:

Here is a breakdown of the above Python code:

• Function definition:
• The code defines a function named "check_last_digit()" that checks if the last digits of the sum of 'x' and 'z' are equal to the last digit of 'y'.
• String Conversion and Last Digit Extraction:
• The function converts the sum of 'x' and 'z' to a string, extracts the last digit using [-1], and compares it with the last digit of 'y'.
