Recursion vs. Tail Recursion vs. Loop

Question

Suppose you are working for a software company having a system with limited memory and you have been given a task. You are using a recursive function to complete the task but you realize that you can use tail recursion instead of a recursive function and then you realize that this tail recursion can be converted to loop.

Now the question is that which of the following technique is best for the above-given scenario and why?
1. Recursive Function.
2. Tail Recursion.
3. Loop.

Answer 1

I know Scheme uses Tail recursion to implement all looping. this eliminates a lot of unnecessary stack frame generation of regular recursion
