题目: 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. More practice: If you have…

目录 题目链接 注意点 解法 小结 题目链接 Maximum Subarray - LeetCode 注意点 最大值有可能是正负数交替着出现 解法 解法一:一次遍历即可.当sum小于0的时候就重新开始求和,因为sum小于0再加上一个数字绝对不可能是max(即sum+nums[i] < nums[i])时间复杂度为O(n) class Solution { public: int maxSubArray(vector<int>& nums) { int max = nums[0],…
