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.
只需要比较现在的数和加上数之后的和就可以。
public class Solution { public int maxSubArray(int[] nums) { int[] dp=new int[nums.length]; dp[0]=nums[0]; int max=dp[0]; for(int i=1;i<nums.length;i++) { dp[i]=Math.max(dp[i-1]+nums[i],nums[i]); max=Math.max(dp[i],max); } return max; } }
