LeetCodeArrayGreedySegment TreeHeap (Priority Queue)Open on judge ↗

You are given an integer array nums of length n and an integer k. You must select exactly k distinct subarrays nums[l..r] of nums. Subarrays may overlap, but the exact same subarray (same l and r) cannot be chosen more than once. The value of a subarray nums[l..r] is defined as: max(nums[l..r]) - min(nums[l..r]). The total value is the sum of the values of all chosen subarrays. Return the maxi
