WebApr 24, 2015 · Tail recursion was identified originally (afaik) as a situation where compilers could speed up execution by replacing them by a loop, and saving on stack management. It is only what the name says: a tail recursion, i.e. a recursive call that is the last thing done by the function before returning. It is a property of the source code. WebExample 1: Not eligible for tail recursion because the function call to itself n*factorial (n-1) is not the last operation. Example 2: Eligible for tail recursion because function call to itself fibonacci (n-1, a+b, a) is the last operation. To tell compiler to perform tail recursion in Kotlin, you need to mark the function with tailrec modifier.
