When a problem can be solved both recursively and iteratively with similar programming effort, it is generally best to use an iterative approach.

Question

Quizplus · Accepted Answer

Iterative solutions are often more efficient in terms of memory usage because they don't involve the overhead of multiple function calls and call stack management that recursive solutions do. This can lead to better performance and less risk of stack overflow errors for problems that can be solved either way.
