题目描述

Find the contiguous subarray within an array (containing at least one number) which has the largest sum.

For example, given the array[−2,1,−3,4,−1,2,1,−5,4],

the contiguous subarray[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.

class Solution {
public:
    int maxSubArray(int A[], int n) {
        int v = ;
        int result = INT_MIN;

        for(int i=;i<n;++i)
         {
             v = max(v+A[i],A[i]);
             result = max(result,v);
         }
        return result;
    }
};
