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. More practice:…

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. SOLUTION 1: 采用滑…

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. 这是动态规划的一道较简单的…

Dynamic Programming There is a nice introduction to the DP algorithm in this Wikipedia article. The idea is to maintain a running maximum smax and a current summation sum. When we visit each num in nums, addnum to sum, then update smax if necessary o…

题意: 给一个序列,求至少含一个元素的最大子段和? 思路: 跟求普通的最大子段和差不多,只不过需要注意一下顺序.由于至少需要一个元素,所以先将ans=nums[0].接下来可以用sum求和了,如果小于0就重置为0,表示重新开始累加.注意代码中两个if的顺序不可以呼唤. class Solution { public: int maxSubArray(vector<int>& nums) { , ans=nums[]; ; i<nums.size(); i++) { sum+=nu…
