第一种是prefix sum + 双指针。 例如Minimum Size Subarray Sum - LeetCode: Given an array of n positive integers and a positive integers, find the minimal length of a contiguous subarray of which the sum ≥s. If there isn't one, return 0 instead. 用O(N)时间得到一个prefix sum array,可...
the contiguous subarray[4,−1,2,1]has the largest sum =6. 分析:这道题是到很经典的题,关键点是要明白sum为负数的连续subarray对可能的最大值没有帮助(除该连续subarray的sum为largest sum外)。所以很简单的,如果sum小于0,我们便置sum为0。代码如下: classSolution {public:intmaxSubArray(intA[],intn...
Given an integer arraynums, find the contiguous subarray (containing at least one number) which has the largest sum and return its sum. Example: Input:[-2,1,-3,4,-1,2,1,-5,4], Output:6 Explanation:[4,-1,2,1]has the largest sum =6. Follow up: If you have figured out the O...
题目: Given an integer array with no duplicates. A maximum tree building on this array leetcode(53):Maximum Subarray 题目Maximum Subarray Easy Given an integer array nums, find the contiguous subarray (containing at least one number) which has the largest sum and return its sum. Example: ...
Can you solve this real interview question? Maximum Subarray - Given an integer array nums, find the subarray with the largest sum, and return its sum. Example 1: Input: nums = [-2,1,-3,4,-1,2,1,-5,4] Output: 6 Explanation: The subarray [4,-1,2,1]
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...
