Given the arrayContinue reading “[Leetcode]1508. Range Sum of Sorted Subarray Sums”numsconsisting ofnpositive integers. You computed the sum of all non-empty continous subarrays from the array and then sort them in non-decreasing order, creating a new array ofn * (n + 1) / 2numbers. Return the sum of the numbers from indexleftto indexright(indexed from 1), inclusive, in the new array. Since the answer can be a huge number return it modulo 10^9 + 7.
