What are some common mistakes in recursive functions?

What are some common mistakes in recursive functions?

Some common mistakes include forgetting the base case, incorrect recursive calls, and excessive memory usage.

Can you explain why the base case is so important?

The base case prevents infinite recursion by providing a condition under which the function stops calling itself.

What happens if I forget to include a base case?

If you forget the base case, the function will keep calling itself indefinitely, leading to a stack overflow error.

How can I optimize a recursive function?

You can optimize it by using techniques like memoization or converting it to an iterative solution.
