You are given an array of positive integersarr. Perform some operations (possibly none) onarrso that it satisfies these conditions: The value of the first element inarrmust be1. The absolute difference between any 2 adjacent elements must be less than or equal to1. In other words,abs(arr[...
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 ...
[leetcode] 795. Number of Subarrays with Bounded Maximum Description We are given an array A of positive integers, and two positive integers L and R (L <= R). Return the number of (contiguous, non-empty) subarrays such that the value of the maximum array element in that subarray is ...
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. ...
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....
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 from it so that there is still at least one element left and the sum of ...

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. ...
Given an array of integers, return the maximum sum for anon-emptysubarray (contiguous elements) with at most one element deletion. In other words, you want to choose a subarray and optionally delete one element from it so that there is still at least one element left and the sum of the ...
