Description Given the array nums consisting of n positive 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 of n * (n + 1) / 2 numbers. Return the sum of the numbers from index left to...
Leetcode__1508. Range Sum of Sorted Subarray Sums 这一题是一道十分典型的二分查找与双指针的使用,题目的大意是,给出一个数组numsnums, 我们可以通过该数组得到子数组, 子数组的大小从 1 到nn, 因此有n(n+1)2n(n+1)2个不同的子数组, 然后我们要求这些子数组的和, 然后对这些子数组的和进行排序, 求...
