What are the use cases for recursion?

Can you explain what recursion is?

Recursion is a programming technique where a function calls itself to solve a problem.

What are some practical use cases for recursion?

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

Can you give an example of recursion in a sorting algorithm?

Sure! QuickSort is a classic example where the array is divided into smaller sub-arrays, and the sort function is called recursively.

Are there any downsides to using recursion?

Yes, recursion can lead to high memory usage and stack overflow if the recursion depth is too high.
