Counting Maximum Bitwise-OR Subsets In PHP
Count Number of Maximum Bitwise-OR Subsets: Calculate max bitwise OR, enumerate subsets (2^n), count valid subsets with max OR. PHP solution for arrays up to size 16.
2044. Count Number of Maximum Bitwise-OR Subsets Difficulty: Medium Topics: Array, Backtracking, Bit Manipulation, Enumeration Given an integer array nums, find the maximum possible bitwise OR of a subset of nums and return the number of different non-empty subsets with the maximum bitwise OR. An array a is a subset of an array b if a can be obtained from b by deleting some (possibly zero) elements of b. Two subsets are considered different if the indices of the elements chosen are different. The bitwise OR of an array a is equal to a[0] OR a[1] OR ... OR a[a.length - 1] (0-indexed). Example 1...
