"WebRecursion and Backtracking. When a function calls itself, its called Recursion. It will be easier for those who have seen the movie Inception. Leonardo had a dream, in that dream he had another dream, in that dream he had yet another dream, and that goes on. So it's like there is a function called d r e a m (), and we are just calling it in itself. " - Space complexity of factorial using recursion

WebSpace Complexity In the recursive program, due to each recursive call, some memory gets allocated in the stack to store parameters and local variables. As there are O (N) recursive calls, the space complexity using recursion is O (N). No extra memory gets allocated in the iterative program, so its space complexity is O (1). Web5. júl 2015 · I'm sorry for reviving an old question, but I think a mistake might be made here that is repeated over and over. As far as I know, computational complexity is defined over the size of an efficient encoding of the input (n).Given an input number m for for factorial, it is true that the algorithm requires m multiplications. But this is not of linear order (i.e. the …
