问题简介 本文将介绍计算机算法中的经典问题——最大子数组问题(maximum subarray problem)。所谓的最大子数组问题,指的是:给定一个数组A,寻找A的和最大的非空连续子数组。比如,数组 A = [-2, -3, 4, -1, -2…
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. 这个题目思路跟[LeetCode] 198. House...

Explanation: Subarray [4, −1, 2, 1] is the max sum contiguous subarray with a sum of 6. We would tackle this problem in the following two ways: Simple Approach Optimized Approach: Kadane’s Algorithm Simple Approach A simple approach to solving the Maximum Subarray Sum problem involves ...
The maximum subarray problem is one of the nicest examples of dynamic programming application. In this lesson we cover an example of how this problem might be presented and what your chain of thought should be to tackle this problem efficiently. ...
