LeetCodeArrayMathTwo PointersSortingSimulationNumber TheoryOpen on judge ↗

You are given an integer array nums of length n. Construct an array prefixGcd where for each index i: - Let mxi = max(nums[0], nums[1], ..., nums[i]). - prefixGcd[i] = gcd(nums[i], mxi). After constructing prefixGcd: - Sort prefixGcd in non-decreasing order. - Form pairs by taking the smallest unpaired element and the largest unpaired element. - Repeat this process until no more pairs can b
