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, r
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]...

Maximum subarray sumwww.codewars.com/kata/54521e9ec8e60bc4de000d6c/ The maximum sum subarray problem consists in finding the maximum sum of a contiguous subsequence in an array or list of integers: max_sequence([-2, 1, -3, 4, -1, 2, 1, -5, 4]) # should be 6: [4, -1,...
Input:[3,-2,2,-3]Output:3Explanation:Subarray [3] and [3,-2,2] both have maximum sum 3 Example 5: Input:[-2,-3,-1]Output:-1Explanation:Subarray [-1] has maximum sum -1 Note: -30000 <= A[i] <= 30000 1 <= A.length <= 30000 ...
The maximum subarray problem is the task of finding the contiguous subarray within a one-dimensional array of numbers (containing at least one positive number) which has the largest sum. For example, for the sequence of values −2, 1, −3, 4, −1, 2, 1, −5, 4; the contiguous...

Can you solve this real interview question? Maximum Sum of Two Non-Overlapping Subarrays - 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
Hello everyone, 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. ...
Kadane’s algorithm is an efficient algorithm used to find the maximum sum subarray within a given array of integers. It was proposed by computer scientist Jay Kadane in 1984. The algorithm works by maintaining two variables: "max_so_far" and "max_ending_here". "max_so_far" keeps track ...
