What are some practical use cases for recursion in programming?

Recursion is often used in tasks like tree traversal, sorting algorithms, and solving problems like the Fibonacci sequence.

Can you explain how recursion works in tree traversal?

Sure! In tree traversal, recursion allows you to visit each node by calling the function on the left and right children.

What about using recursion for sorting algorithms?

Recursion is key in algorithms like quicksort and mergesort, where the problem is divided into smaller subproblems.

Are there any downsides to using recursion?

Yes, recursion can lead to stack overflow if the recursion depth is too high, and it may be less efficient than iterative solutions.
