Maximum Subarray
Easy
Given an integer array
nums
, find the contiguous subarray (containing at least one number) which has the largest sum and return its sum.Example:
1
2
3
4 > Input: [-2,1,-3,4,-1,2,1,-5,4],
> Output: 6
> Explanation: [4,-1,2,1] has the largest sum = 6.

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