What are the best practices for using recursion in programming?

Some best practices for recursion include ensuring a base case, avoiding excessive recursion depth, and using tail recursion when possible.

Can you explain what a base case is?

A base case is a condition in a recursive function that stops the recursion from continuing indefinitely. It's essential for preventing stack overflow.

What are the risks of deep recursion?

Deep recursion can lead to stack overflow errors, as each recursive call consumes stack space. It's important to limit recursion depth.

How can I optimize recursive functions?

You can optimize recursive functions by using memoization to store results of expensive function calls and avoid redundant calculations.
