How is recursion used in data structures?

Can you explain how recursion is used in data structures?

Sure! Recursion is a technique where a function calls itself to solve smaller instances of the same problem. In data structures, it's often used with trees and linked lists.

Can you give me an example of recursion in a binary tree?

Absolutely! A common example is traversing a binary tree. You can use recursion to visit each node, like in an in-order traversal where you visit the left child, then the node, and finally the right child.

What are the advantages of using recursion?

Recursion can simplify code and make it easier to read. It also allows for elegant solutions to problems that have a natural recursive structure, like tree traversals.

Are there any downsides to using recursion?

Yes, recursion can lead to high memory usage due to the call stack, and it may cause stack overflow errors if the recursion depth is too high.
