2571. Minimum Operations to Reduce an Integer to 0

You are given a positive integer n, you can do the following operation any number of times: - Add or subtract a power of 2 from n. Return the minimum number of operations to make n equal to 0. A number x is power of 2 if x == 2i where i >= 0. Example 1: Input: n = 39 Output: 3 Explanation: We can do the following operations: - Add 20 = 1 to n, so now n = 40. - Subtract 23 = 8 from n, so now
