Can you solve this real interview question? Maximum Element After Decreasing and Rearranging - 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 fir
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 at least L and at most R. Example :Input:A = [2, 1, 4, 3]...
怎样避免Leetcode 318题中的常见错误? 文章作者:Tyan 博客:noahsnail.com | CSDN | 简书 1. Description 2. Solution 解析: Version 1每次迭代都需要进行两次set转换,Version 2预先进行了set转换,效率有提升。由于Version 2中两个字符串的与运算非常耗时,因此Version 3先将字符串转换为代表字符串的数字,然后进行...
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....

What map.containsKey(sum - k) returns is the index where the sum of every element up to that index from index 0 is sum - k, or (7 - 3) == 4, in our example. Let’s say that that index returned by map.containsKey(sum - k) is 2 (randomly chose one that is before index 5...
LeetCode "Sliding Window Maximum" Monotonic Queue is getting more popular, and finally LeetCode put it on. Typical Solution: element in array will be pushed\popped in\from a sorted data structure, which points to multiset(or any heap-like data structure). Complexity is O(nlgn)....
