0053.maximum-subarray

README

Given an integer array nums, find the subarray which has the largest sum and return its sum.

Example 1:

Input: nums = [-2,1,-3,4,-1,2,1,-5,4] Output: 6 Explanation: [4,-1,2,1] has the largest sum = 6.

Example 2:

Input: nums = [1] Output: 1

Example 3:

Input: nums = [5,4,-1,7,8] Output: 23

Constraints:

1 <= nums.length <= 105 -104 <= nums[i] <= 104

Follow up: If you have figured out the O(n) solution, try coding another solution using the divide and conquer approach, which is more subtle.
