What are some real-world examples of recursion?

Recursion is a process where a function calls itself. Common examples include calculating factorials, navigating file systems, and the Fibonacci sequence.

Can you explain how recursion works in a file system?

Sure! In a file system, recursion allows you to traverse directories. For example, to list all files in a directory and its subdirectories, a function can call itself for each subdirectory.

What about recursion in programming languages?

Many programming languages support recursion. For instance, in Python, you can define a function that calls itself to solve problems like searching through data structures or implementing algorithms.

Are there any downsides to using recursion?

Yes, recursion can lead to high memory usage and stack overflow errors if the recursion depth is too high. It's important to consider these factors when using it.
