As such, tail recursive functions can often be easily implemented in an iterative manner; by taking out the recursive call and replacing it with a loop, the same effect can . The base case returns a value without making any subsequent calls. The tail-recursive functions considered better than non-tail recursive functions as tail-recursion can be optimized by the compiler. Recursion is a computer programming technique involving the use of a procedure, subroutine, function, or algorithm that calls itself in a step having a termination condition so that successive repetitions are processed up to the critical step where the condition is met at which time the rest of each repetition is processed from the last one Once unpublished, all posts by sloan will become hidden and only accessible to themselves.
