Welcome to the challenge problems! Here, we'll test your knowledge of loops from Lesson 5...
Here we'll include three problems that you can answer:
Problem 1: Write a for loop that counts from 1 to 100. It should print out ONLY the even numbers from 1 to 100.
Problem 2: Change the for loop in problem 1 to not include any if statements.
Problem 3: Change the loop in problem 2 to become a while loop.
