Head rekursion

WebHead Recursion: If a recursive function is calling itself and the recursive call is the first statement in the function, then it is called Head recursion. There is no statement or instructions before the recursive call. In head recursion, all the operations are performed at the returning time and no operations are performed at the calling time.

WebNon-tail Recursion is defined as a recursive function in which the first statement is a recursive call and then the other operations are performed. It is also called Head Recursion. Non-tail Recursion does not perform any operation at the time of recursive calling. Instead, all operations are done at the return time. WebIn tail recursion, the recursive step comes last in the function—at the tail end, you might say. The function checks for the base case and returns if it's successful. Then at the end of the function—the tail —the recursive case runs only if the base case hasn't been reached.
