Webb26 juli 2024 · The running time complexity for the program to find the power of the number using recursion is O(logn) because every time the recursive function is called, the parameter of the next call is increased by exponential times. Therefore, the time complexity is the function of the log. 4) Reverse A Number Using Recursion In C++ Webb13 nov. 2011 · The only major correction I see that needs to be made is that on line 34, the second parameter to the raising () call should be -y-1, not y-1.
