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...
In a given array nums of positive integers, find three non-overlapping subarrays with maximum sum. Each subarray will be of size k, and we want to maximize the sum of all 3*k entries. Return the result as a list of indices representing the starting position of each interval (0-indexed)...
Input: [-2,-3,-1] Output: -1 Explanation: Subarray [-1] has maximum sum -1 Note: -30000 <= A[i] <= 30000 1 <= A.length <= 30000 这道题比较好理解,关于最大子数组的解法 可以参考 int maxSubArray(vector<int>& A) { int ans = INT_MIN; int cur = INT_MIN; for (int k ...
In a given arraynumsof positive integers, find three non-overlapping subarrays with maximum sum. Each subarray will be of sizek, and we want to maximize the sum of all3*kentries. Return the result as a list of indices representing the starting position of each interval (0-indexed). If ...
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...
I would like to quickly compute maximum sum subarray with queries (changeith element tox). Can we do it faster thanO(log(n))per query? The answer is no, and here is the reasoning. You can answer this question using some logic by reducing the problem to a known one. ...

Given an integer array nums and two integers firstLen and secondLen, return the maximum sum of elements in two non-overlapping subarrays with lengths firstLen and secondLen. The array with length firstLen could occur before or after the array with length secondLen, but they have to be non...
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...
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...
