LeetCodeArrayDynamic ProgrammingBit ManipulationBitmaskOpen on judge ↗

You are given a 0-indexed integer array nums containing n distinct positive integers. A permutation of nums is called special if: - For all indexes 0 <= i < n - 1, either nums[i] % nums[i+1] == 0 or nums[i+1] % nums[i] == 0. Return the total number of special permutations. As the answer could be large, return it modulo 109 + 7. Example 1: Input: nums = [2,3,6] Output: 2 Explanation: [3,6,2]
