WebJul 11, 2024 · Tail call optimization reduces the space complexity of recursion from O (n) to O (1). Our function would require constant memory for execution. It does so by eliminating the need for having a separate stack frame for every call. If a function is tail recursive, it's either making a simple recursive call or returning the value from that call. WebApr 13, 2024 · Space Complexity in case of recursion: When any function call is made, the function call gets pushed onto a call stack. When the called function returns to the calling function then the function call gets popped from the call stack. The avg total number of function calls at any moment in the stack represents the space complexity. Thus here ...
