In computer science, the maximum sum subarray problem is the task of finding a contiguous subarray with the largest sum, within a given one-dimensional array A[1...n] of numbers. Formally, the task is to find indices and with, such that the sum is as large as possible. Example: Input...
17.8 You are given an array of integers (both positive and negative). Find the contiguous sequence with the largest sum. Return the sum. LeetCode上的原题,请参见我之前的博客Maximum Subarray。 解法一: intget_max_sum(vector<int>nums) {intres = INT_MIN, sum =INT_MIN;for(auto a : nums)...
