### power using recursion geeksforgeeks

It contains well written, well thought and well explained computer science and programming articles, quizzes and practice/competitive programming/company interview … Example 2: Input: str = "aa" Output: a a aa Explanation : There are 3 substrings that can be formed from aa. To understand this example, you should have the knowledge of the following C programming topics: A Computer Science portal for geeks. So we need a function that inserts at the bottom of a stack using the above given basic stack function. Dynamic Programming is mainly an optimization over plain recursion. ... We need to be careful not to call the recursion more than once, because using several recursive calls in one step creates exponential complexity that cancels out with using a fraction of n. Example 1: Input: N = 2 Output: 4 Explanation: The reverse of 2 is 2 and after raising power of 2 by 2 we get 4 which gives remainder as 4 by dividing 1000000007. void insertAtBottom((): First pops all stack items and stores the popped item in function call stack using recursion.
