532. K-diff Pairs in an Array 一、问题描述 Given an array of integers and an integer k, you need to find the number of unique k-diff pairs in the array. Here a k-diff pair is defined as an integer pair (i, j), where i and j are both numbers in the array and their absolute...
LeetCode算法题-K-diff Pairs in an Array(Java实现) 这是悦乐书的第254次更新,第267篇原创 01 看题和准备 今天介绍的是LeetCode算法题中Easy级别的第121题(顺位题号是532)。给定一个整数数组和一个整数k,您需要找到数组中唯一的k-diff对的数量。 这里k-diff对被定义为整数对(i,j),其中i和j都是数组中...
Given an array of integers and an integer k, you need to find the number of unique k-diff pairs in the array. Here a k-diff pair is defined as an integer pair (i, j), where i and j are both numbers in the array and theirabsolute differenceis k. Example 1: Input: [3, 1, 4...
532.K-diff Pairs in an Array 解题思路。 1、读题,数组中二数之差的绝对值为k。 2、只要遍历数组,每一个元素加上K值,还在原来的数组中,就找到一个解。 3、如果用数组遍历,会超时,通不过LeetCode 的测试,变…

Can you solve this real interview question? Divide Array Into Equal Pairs - You are given an integer array nums consisting of 2 * n integers. You need to divide nums into n pairs such that: * Each element belongs to exactly one pair. * The elements p
Can you solve this real interview question? Restore the Array From Adjacent Pairs - There is an integer array nums that consists of n unique elements, but you have forgotten it. However, you do remember every pair of adjacent elements in nums. You are g
All the numbers in the input array are in the range of 32-bit integer. ReversePairs是LeetCode Weekly Contest 19的最后一题,很可惜没有做出来。这篇文章就是针对此类数组问题做出的总结。 解决复杂的数组类问题主要思想就是动态规划:将数组拆分,解决子问题。
