What's So Good About Recursion? [duplicate]

Question

Is there a performance hit if we use a loop instead of recursion or vice versa in algorithms where both can serve the same purpose? Eg: Check if the given string is a palindrome. I have seen many programmers using recursion as a means to show off when a simple iteration algorithm can fit the bill. Does the compiler play a vital role in deciding what to use?

Answer 1

Loops may achieve a performance gain for your program. Recursion may achieve a performance gain for your programmer. Choose which is more important in your situation!
