In the first step of the algorithm, we need to calculate f 1 for every possible argument p and then sort the values. Thus, this step has complexity: O ( ⌈ m n ⌉ ( log m + log ⌈ m n ⌉)) = O ( ⌈ m n ⌉ log m)

WebBinary Exponentiation is a technique of computing a number raised to some quantity in a fast and efficient manner. It uses properties of exponentiation and binary numbers for … WebImplement pow (x, n), which calculates x raised to the power n (i.e., x n ). Example 1: Input: x = 2.00000, n = 10 Output: 1024.00000 Example 2: Input: x = 2.10000, n = 3 Output: 9.26100 Example 3: Input: x = 2.00000, n = -2 Output: 0.25000 Explanation: 2 -2 = 1/2 2 = 1/4 = 0.25 Constraints: -100.0 < x < 100.0 -2 31 <= n <= 2 31 -1 n is an integer.
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:
