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.
A[i]有两种选择
1.新开一个数组；
2.加入原有数组max ＋a［i］；
public class Solution { public int maxSubArray(int[] A) { int max_here=A[0]; int max_sofar=A[0]; for(int i=1;i<A.length;i++){ max_here=Math.max(max_here+A[i],A[i]); max_sofar=Math.max(max_here, max_sofar); } return max_sofar; } }
