Dijkstra was right — recursion should not be difficult

WebYes, because recursive_function (x) takes the answer from recursive_function ( x-1), recursive_function (x-2) and manipulates it into the right answer for recursive_function (x) 4. This covers every possible value of x. Yes, because our cases cover the lowest permitted values of x and we never accidentally skip them. Web15 nov. 2024 · From what I understand there is no recursive algorithm for which no iterative implementation exists that is at least as performant (as you can simply "simulate" recursion iteratively, when managing the stack within the loop).
