Explanation: We just choose [3] and it's the maximum sum. Example 3: Input: arr = [-1,-1,-1,-1] Output: -1 Explanation: The final subarray needs to be non-empty. You can't choose [-1] and delete -1 from it, then get an empty subarray to make the sum equals to 0. Cons...

有了FIND-MAX-CROSSING-SUBARRAY我们可以找到跨越中点的最大子数组,于是,我们也可以设计求解最大子数组问题的分治算法了,其伪代码如下: FIND-MAXMIMUM-SUBARRAY(A, low, high): if high = low return (low, high, A[low]) else mid = floor((low+high)/2) (left-low, left-high, left-sum) = FIND...
https://leetcode.com/problems/maximum-subarray/ 题目描述 Given an integer array nums, find the contiguous subarray (containing at least one number) which has the largest sum and returnits sum. Example 1: Input: nums=[-2,1,-3,4,-1,2,1,-5,4] Output:6 ...
题目Given an integer array nums, find the contiguous subarray (containing at least one number) which has the largest sum and return its sum. A subarray is a contiguous part of an array. Example 1: I…
leetcode || 53、Maximum Subarray problem: Find the contiguous subarray within an array (containing at least one number) which has the largest sum. For example, given the array [−2,1,−3,4,−1,2,1,−5,4], the contiguous subarray [4,−1,2,1] has the largest sum = 6....
