What are some real-world examples of tail recursion?

Tail recursion is a technique where a function calls itself as its last action. A common example is calculating factorials.

Can you give me a specific programming language example?

Sure! In Python, you can implement tail recursion for calculating the factorial like this: def factorial(n, acc=1): return factorial(n-1, n*acc) if n > 1 else acc.

Are there any performance benefits to using tail recursion?

Yes, tail recursion can optimize memory usage since it allows the compiler to reuse stack frames, preventing stack overflow.

What languages support tail call optimization?

Languages like Scheme, Haskell, and some implementations of JavaScript support tail call optimization, improving performance.
