[LintCode] Subarray Sum Closest Given an integer array, find a subarray with sum closest to zero. Return the indexes of the first number and last number. Example Given [-3, 1, 1, -3, 5], return [0, 2], [1, 3], [1, 1], [ 2, 2] or [0, 4] Challenge O(nlogn) time ...

Leetcode 53. Maximum Subarray 2. Solution **解析:**Version 1,简单粗暴,前i个元素总和大于0,则这些元素对总和是有贡献的,要保留,否则,则丢弃前i个元素。重新开始执行上述操作,每次加完记得更新最大值。Version 2,采用动态规划求解,首先定义状态,dp[i]是以nums[i]为结尾的连续子数组的最大和,状态转移方程...

The maximum sum subarray problem is to find a contiguous subarray with the largest sum. The history of algorithms to address this problem is recounted, culminating in what is known as Kadane’s algorithm. However, that algorithm is not the algorithm Kadane intended. Nonetheless, the algorithm kno...
