Recursion Hack

def factorial(n):
    # Check for edge cases
    if not isinstance(n, int) or n < 0:
        return "Error: Factorial is only defined for non-negative integers."
    elif n == 0 or n == 1:  # Base cases
        return 1
    else:
        return n * factorial(n - 1)  # Recursive call

# Input for a number between 9 and 13
number = 11
result = factorial(number)

# Display the result with a custom message
if isinstance(result, int):
    print(f"The factorial of {number} is {result}.")
else:
    print(result)

Iterating over a List Hack

# Define the list of numbers
numbers = [1, 2, 3, 4, 5]

# Iterate through the list and print each number
for number in numbers:
    print(number)

1
2
3
4
5

Iterating over a list using loops and printing a message HACK

# List of colors
colors = ["red", "blue", "green", "yellow"]

# Iterate through the list and print each color
for color in colors:
    print(color)


red
blue
green
yellow

Breaking Loops HACK

# List of numbers
numbers = [1, 2, 3, 4, 5]

# Iterate through the list
for number in numbers:
    if number == 3:
        continue  # Skip the number 3
    elif number == 5:
        break  # Stop the loop when 5 is encountered
    print(number)
