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.

WebExponentiation is a mathematical operation that is expressed as x n and computed as x n = x ⋅ x ⋅... ⋅ x ( n times). Basic method While calculating x n, the most basic solution is broken down into x ⋅ x n − 1. The new problem is x n − 1, which is similar to the original problem. 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.

WebJan 11, 2024 · Space Complexity: O (1) Solution 2: Binary exponentiation. 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. dynasty warriors 9 empires no soundWebExample 1: Input: a = 1, b = 1 Output: 1 Explanation: 11 % (109+7) = 1. ​Example 2: Input: a = 2, b = 5 Output: 32 Explanation: 25 % (109+7) = 32.
