Problem

Given a stack of integers, write a function that returns the sum of all the integers in the stack.
Example input:
[1, 2, 3, 4, 5]
Example output:
15

Solution

def sum_stack(stack):
    
    This function takes a stack of integers and returns the sum of all the integers in the stack.
    
    # Initialize the sum variable
    sum = 0
    # Iterate through the stack
    for i in stack:
        # Add the current value to the sum
        sum += i
    # Return the sum
    return sum

# Test the function
print(sum_stack([1, 2, 3, 4, 5]))
