Leetcode 53. Maximum Subarray (largest sub-array)

Kadane algorithm, Kadane algorithm is, if the previous sum is less than 0, recalculate sum, if sum is not less than 0, then continue to add. Then look at the divide and conquer method: There are three possibilities for any array: 1. Its maximum subarray falls on its left side; 2. Maximum Subarray falls on its right side; 3.    Maximum Subarray falls in the middle of it.    For the first, two cases, the use of dichotomy is easy to get, base case is if there is only one number, then return. For t
