Exponential Squaring (Fast Modulo Multiplication)
WebIf there are 0 or more than 1 set bit the answer should be -1. Position of set bit '1' should be counted starting with 1 from LSB side in binary representation of the number. Example 1: Input: N = 2 Output: 2 Explanation: 2 is represented as "10" in Binary. As we see there's only one set bit and it's in Position 2 and thus the Output 2. Example 2: WebThis problem is a programming version of Problem 122 from projecteuler.net. The most naive way of computing requires fourteen multiplications: But using a "binary" method you can compute it in six multiplications: However it is yet possible to compute it in only five multiplications: We shall define to be the minimum number of multiplications ... WebThe task is to check if N is a power of 2. More formally, check if N can be expressed as 2x for some x. Example 1: Input: N = 1 Output: YES Explanation:1 is equal to 2 raised to 0 (20 = 1). Example 2: Input: N = 98 Output: NO Explanation: 98 cannot be obtained by any power of 2. Your Task:Your task is to complete the function isPowerofTwo ... christi weston
