WebMar 18, 2024 · Tail recursion and tail-call optimization. To keep the memory footprint to a minimum, some languages—like Erlang and thus Elixir—implement tail-call optimization. With a small rewrite of our code, we can prevent the stack frame being added and that memory allocated. This example is yet another implementation of the function from before. WebDec 29, 2024 · Generally speaking, we can separate recursion problems into head and tail recursion. Head recursion carries the risk of a stack overflow error, should the recursion go quite deep. In this tutorial, we’ll show how Scala’s tail recursion optimizations can address this issue by reducing the call stack to just one frame. 2. Calculating List Length

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.
