Time Complexity: O(n) where n is size of the string Auxiliary Space: O(n) where n is the size of string, which will be used in the form of function call stack of recursion. Smallest string without any multiplication sign that represents the product of two given numbers. The function has to process or perform any operation at the time of calling and it does nothing
After that call the recursive function performs nothing. Below are the detailed example to illustrate the difference between the two: Time Complexity: Finding the Time complexity of Recursion is more difficult than that of Iteration. Click me to see the solution.
