Intuition: While calculating (n^k), binary exponentiation relies on whether n is even or odd. If k is even (n k) can be written as (n 2) k/2. As we can see that computation steps were reduced from k to k/2 in just one step. If k is odd (n k) can be written as n.

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 … 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: flint cleaners https://growstartltd.com
