## LeetCode 53 最大子数列和 Maximum Subarray class Solution(): def maxSubArray(self, nums): l = len(nums) dp = [0] * l ## 初始化数组全部为0 ## 套路第三步,初始特殊值为 nums 第一个元素 dp[0] = nums[0] #res_max = dp[0] ## 最终结果也初始化为 nums
Description 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. Analysis 题目隶属于分治类型之下,所以最开始就会从“...
Given an integer array nums, find the contiguous subarray (containing at least one number) which has the largest sum and return its sum. Example: Input: [-2,1,-3,4,-1,2,1,-5,4], Output: 6 Explanation: [4,-1,2,1] has the largest sum = 6. Follow up: If you have figured ...
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: If you have figured out the O(n) solution, try coding another solution using the divide and conquer approach, which is more subtle. [解题...

Given an integer array nums, find the contiguous subarray (containing at least one number) which has the largest sum and return its sum.
dp[0] = nums[0]。优化后的动规 - 用当前位置来保存以当前位置结尾的最大子数组 Python 代码：时间复杂度：O(n)空间复杂度：O(1) ~ 不使用额外的空间 解法三：分治算法 Divide and Conquer 思路：虽然复杂，但速度不太行，只是比暴力算法好一些。时间复杂度据说是 O(nlogn)。
