Note: Recursion is required in Part 2 of the problem, not in Part 1 (but you'll need to solve Part 1 to unlock Part 2). Also, fully solving this problem is challenging, but there are some intermediate ...

Here we go(go(go()))! It's time to flex your coding muscles on recursion. For each problem, implement a recursive function that satisfies all the listed requirements. Iterative solutions will be ...
