How can I optimize tail recursion in my code?

To optimize tail recursion, ensure that the recursive call is the last operation in the function. This allows the compiler to reuse the current function's stack frame.

Can you give me an example of a tail recursive function?

Sure! Here's a simple example in Python:

def factorial(n, accumulator=1):
    if n == 0:
        return accumulator
    return factorial(n-1, n * accumulator)

What are the benefits of using tail recursion?

The main benefits are reduced stack space usage and improved performance, as it can prevent stack overflow errors in deep recursions.

Are there languages that optimize tail recursion automatically?

Yes, languages like Scheme and some implementations of Scala optimize tail recursion automatically, allowing for more efficient recursive calls.
