For array of 1 element, there is 1 way for each different number choice with a search cost of 1. This is true because maximum value is initially set to < 0, so any number choice will incur an update. dp[0][1][maxV] = 1, maxV in [1, m]. Answer: Sum of dp[n - 1][k]...
方法二:分治 Step1. Select the middle element of the array. So the maximum subarray may contain that middle element or not. Step 2.1 If the maximum subarray does not contain the middle element, then we can apply the same algorithm to the the subarray to the left of the middle element and...
For example, if we have pairs(1,5),(2,3), and(4,4), the maximum pair sum would bemax(1+5, 2+3, 4+4) = max(6, 5, 8) = 8. Given an arraynumsof even lengthn, pair up the elements ofnumsinton / 2pairs such that: Each element ofnumsis in exactly one pair, and The ...
1186 Maximum Subarray Sum with One Deletion 删除一次得到子数组最大和 Description: Given an array of integers, return the maximum sum for a non-empty subarray (contiguous elements) with at most one element deletion. In other words, you want to choose a subarray and optionally delete one element...
Leetcode: Maximum Product Subarray 题目: Find the contiguous subarray within an array (containing at least one number) which has the largest product. For example, given the array [2,3,-2,4], the contiguous subarray [2,3] has the largest product = 6....
Another simple way to find the maximum subarray is dynamic programming. If we can use DP to calculate the presum of the array (every subarray with start from the first element), we only need to find the maximum increase in the presum array. ...

Description: Given an array nums of positive integers, return the longest possible length of an array prefix of nums, such that it is possible to remove exactly one element from this prefix so that every number that has appeared in it will have the same number of occurrences. ...
1846. Maximum Element After Decreasing and Rearranging # 题目 # You are given an array of positive integers arr. Perform some operations (possibly none) on arr so that it satisfies these conditions: The value of the first element in arr must be 1. The
LeetCode 325. Maximum Size Subarray Sum Equals k 嘻嘻一只小仙女呀 Be cool. But also be warm.✨6 人赞同了该文章 题目: Given an array nums and a target value k, find the maximum length of a subarray that sums to k. If there isn't one, return 0 instead. Note:The sum of the ent...
