53. Maximum Subarray
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
.
最大子序列和。
dp[i] = max(dp[i-1]+nums[i],nums[i]);代表以i结尾的最大和。
class Solution {public: int maxSubArray(vector<int>& nums) { int n = nums.size(); vector<int> dp(n); int Max = INT_MIN; dp[0] = nums[0]; for (int i = 1; i < n; ++i) { int x = dp[i - 1] + nums[i]; dp[i] = (x > nums[i]) ? x : nums[i]; } for (int i = 0; i < n; ++i) { Max = max(Max, dp[i]); } return Max; }};
