WebMay 19, 2024 · Tail recursion is the act of calling a recursive function at the end of a particular code module rather than in the middle. A function is recursive if it calls itself. This programming concept is often useful for self-referencing functions and plays a major role in programming languages such as LISP.

WebIf the target of a tail is the same subroutine, the subroutine is said to be tail recursive, which is a special case of direct recursion. Tail recursion(or tail-end recursion) is particularly useful, and is often easy to optimize in implementations. Tail calls can be implemented without adding a new stack frameto the call stack. WebNon-tail Recursion does not perform any operation at the time of recursive calling. Instead, all operations are done at the return time. Let us take an example of Non-tail Recursion and understand how its done: void fun(int n) { if (n>0){ fun(n-1); printf (" %d", num); } } ppt background design wood
