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...
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 index righ...
Can you solve this real interview question? Sum of Subarray Minimums - Given an array of integers arr, find the sum of min(b), where b ranges over every (contiguous) subarray of arr. Since the answer may be large, return the answer modulo 109 + 7. Ex
LeetCode53 Maximum sum of subarray classic dp: dp[i] represents the maximum sum of subarray which ends in nums[i], and dp[i] = Math.max(nums[i], dp[i - 1] + nums[i]). and since we have to include nums[i] due to it’s on the defination of dp[i], and when dp[i-1]<...

LeetCode 325. Maximum Size Subarray Sum Equals k若谷 武汉大学 摄影测量与遥感博士 来自专栏 · 今日事 题目: Given an array nums and a target value k, find the maximum length of a subarray that sums to k. If there isn't one, return 0 instead. Note:The sum of the entire nums ...
在解法一中,对于subarray{i, j}中的每一个值,我们每次都老老实实得一个个加起来,做了大量重复的工作。简单思考后我们发现,只要得到子数组subarray{0, i}和sum_i子数组subarray{0, j}的和sum_j,那么子数组subarray{i, j}的和sum就等于sum_j - sum_i + nums[i](其中0 <= i <= j < n),而且...
