Fast Power Algorithm - Exponentiation by Squaring - C++ and Python Implementation. We know how to find 2 raised to the power 10. But what if we have to find 2 raised to the power very large number such as 1000000000? We discuss how to find solution to such a problem using an fast, efficient algorithm See more Exponentiation by Squaring helps us in finding the powers of large positive integers. Idea is to the divide the power in half at each step. Let’s take an example: Effectively, power is divided by 2 and base is multiplied to itself. … See more We multiply a to itself, b times. That is, a^b = a * a * a * ... * a (b occurrences of a).A simple python implementation of that would be: Notice that … See more By the way, in Python we could have simply used ** operator to find a^b like a**b. However, I just wanted to implement the code so that we can easily port the code in other languages. Now, try and call that function for a = 2 … See more
