此算法和贪心算法有点像,但是又不完全一样:不使用额外的变量来保存 maxSub,而是把 curSum 保存到了当前数字的位置(动规会保存多个临时结果),最后max(所有的curSum)。 Python 代码: ## 用数组本身,来保存结果 class Solution(): ## 动态规划 def maxSubArray(self, nums): for i in range(1, len(nums)...
#53 Maximum Subarray 先尽量正确理解题目:给定一个整数数列 nums, 找到其中具有最大sum的连续子数列片段。 Example: Input: [-2,1,-3,4,-1,2,1,-5,4], Output: 6 Explanation: [4,-1,2,1] has the largest sum …
Leetcode 53. Maximum Subarray 2. Solution **解析:**Version 1,简单粗暴,前i个元素总和大于0,则这些元素对总和是有贡献的,要保留,否则,则丢弃前i个元素。重新开始执行上述操作,每次加完记得更新最大值。Version 2,采用动态规划求解,首先定义状态,dp[i]是以nums[i]为结尾的连续子数组的最大和,状态转移方程...
[Leetcode][python]Maximum Subarray/最大子序和 题目大意 由N 个整数元素组成的一维数组 (A[0], A[1],…,A[n-1], A[n]),这个数组有很多连续子数组,那么其中数组之和的最大值是什么呢? 子数组必须是连续的。 不需要返回子数组的具体位置。
