WebExample 1: Input: N = 1 Output: 1 Explanation: The nearest power of 2 greater than or equal to 1 is 2^0=1. Example 2: Input: N = 5 Output: 8 Explanation: The nearest power of 2 greater than 5 is 2^3=8. Your Task: You don't need to read input or print anything.Your Task is to complete the function nearestPowerOf2 () which takes a number N as ... WebGiven two integers N and M you have to find out an integer which is a power of M and is nearest to N. Note: If there are multiple answers possible to, print the greatest number possible. Example 1: Input: N = 6, M = 3 Output: 9 Explanation: Both 3 (31) and 9 (32) are equally near to 6. But 9 is greater, so the Output is 9.
