Maximum Sum Subarray 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. 代码: 1publicclassSoluti...
Input:[1,-2,3,-2]Output:3Explanation:Subarray [3] has maximum sum 3 Example 2: Input:[5,-3,5]Output:10Explanation:Subarray [5,5] has maximum sum 5 + 5 = 10 Example 3: Input:[3,-1,2,-1]Output:4Explanation:Subarray [2,-1,3] has maximum sum 2 + (-1) + 3 = 4 Example...
求出前缀和,问题变成了O(n*n)复杂度的问题,但是仍然不能解决问题。 设prefix为前缀和,设i < j,一般都是通过算sum = prefix[j] - prefix[i]求和的最大值,但是本题中有取模,要求sum最大。 第一种情况:如果prefix[j] > prefix[i],sum < prefix[j],这种情况就不需要考虑了。 第二种情况:prefix[j]...
is maximum. I would like to find an algorithm with complexity less thanO(n2). For instance, if the array is then the underlined subarray would be the one we are looking for (its "score" is 7×4 = 28) . Notice that if we changed "sum" into "min" the problem would be solvable in...

Can you solve this real interview question? Maximum Sum Circular Subarray - Given a circular integer array nums of length n, return the maximum possible sum of a non-empty subarray of nums. A circular array means the end of the array connects to the beg
Given an array, we need to find two subarrays with a specific length K such that sum of these subarrays is maximum among all possible choices of subarrays. arr size <10^5 n<10^3 Examples: Input : arr[] = [2, 5, 1, 2, 7, 3, 0] ...

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...
Maximum Size Subarray Sum Equals K Given an arraynumsand a target valuek, find the maximum length of a subarray that sums tok. If there isn't one, return 0 instead. Example 1: Givennums=[1, -1, 5, -2, 3],k=3, return4. (because the subarray[1, -1, 5, -2]sums to 3 and...
