Question 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 -- DP New ar…

一.题目说明 题目是53. Maximum Subarray,求最长连续子序列最大和.难度是Easy! 二.我的解答 Easy的题目,居然没做出来. 后来看了用dp方法,其中dp[i]表示以第i个元素结尾的最大和. dp[i] = nums[i] > nums[i]+dp[i-1] ? nums[i] : nums[i]+dp[i-1]; 然后求出最大的dp即可.知道思路,实现非常简单,问题是没有往动态规划上面去想. #include<iostream> #include<vect…

Given an array of integers, find a contiguous subarray which has the largest sum. Notice The subarray should contain at least one number. Have you met this question in a real interview? Yes Example Given the array [−2,2,−3,4,−1,2,1,−5,3], the contigu…

1.   Maximum Subarray (#53) 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 s…

<算法导论>一书中演示分治算法的第二个例子,第一个例子是递归排序,较为简单.寻找maximum subarray稍微复杂点. 题目是这样的:给定序列x = [1, -4, 4, 4, 5, -3, -4, 9, 6 - 4, 6, 4, 3, -5]:寻找一个连续的子序列,使得其和是最大. 这个题目有意义的地方在于,序列X的元素有正有负. 思路很简单,把序列分为相同的两部分A和B,在其内寻找maximum subarray,那么maximum subarray有可能在A中,也有可能在B中,也有…

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:…

In computer science, the maximum subarray problem is the task of finding the contiguous subarray within a one-dimensional array of numbers which has the largest sum. For example, for the sequence of values −2, 1, −3, 4, −1, 2, 1, −5, 4; the contiguou…

间隔2天,继续开始写LeetCodeOj. 原题: Maximum Subarray 其实这题很早就看了,也知道怎么做,在<编程珠玑>中有提到,求最大连续子序列,其实只需要O(n)的复杂度就可以. 今天早上到公司比较早,就写了一下,发现还是有地方忘了: 1. 记得记录当前的最大值,因为局部最大和全局最大是不同的. 2. 记得描述32位int最大值,最小值的方法,最大值是 0x7FFFFFFF,最小值是0x80000000. class Solution { public: int maxSub…
