Self-Explanation

Examine the factorial(num1) function (Step 1):
- Look at the while loop inside this function. Why do you think it is getting stuck in an infinite loop?
- Hint: What should happen to num1 during each loop iteration to eventually stop the loop?
- How can you modify the code to ensure num1 decreases in value each time through the loop? Write down your ideas.
Explain the Fix:
- Once you’ve figured out how to stop the infinite loop, explain what line of code you would add to ensure that num1 eventually becomes 0, allowing the loop to terminate. What role does this line of code play in the overall function?

Step 2: Explore the Modulo Operator

Next, let's think about how you can implement the modulo operator in the next function.

Look at the moduloPractice(num1) function (Step 2):
- The goal here is to return the remainder when num1 is divided by 9. If you’re unsure how the modulo operator works, revisit zyBooks to review it.
- How will you use the modulo operator to find the remainder? Test different numbers (e.g., 81, 4, 64) to see how the remainder changes when you divide by 9.
- Hint: The modulo operator returns the remainder, not the quotient.
