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 difference is k. Exa…

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都是数组中的数字,它们的绝对差是k.例如: 输入:[3,1,4,1,5],k = 2 输出:2 说明:数组中有两个2-diff对,(1,3)和(3,5).虽然我们在输入中有两个1,但我们应该只返回唯一对的数量. 输入:[1,2…

例1: 输入: [3,1,4,1,5],k = 2  输出: 2 说明:阵列中有两个2-diff对,(1,3)和(3,5). 虽然我们在输入中有两个1,但我们应该只返回唯一对的数量. 例2: 输入: [1,2,3,4,5],k = 1  输出: 4 说明:阵列中有四个1-diff对,(1,2),(2,3),(3,4)和(4,5). 例3: 输入: [1,3,1,5,4],k = 0  输出: 1  说明:数组中有一个0-diff对,(1,1). 注意: 对(i,j)和(j,i)计为同一对. 阵列…

写在前面:研究操作系统,习惯了用C,但是在做算法题甚至构建大型系统时,C真的是噩梦.还是用C++比较好,基本算法很成熟,并可基于此实现更复杂的算法.那就边写算法边捡起来好久不用的C++吧! 题目:数组中的k差对(K-diff Pairs).输入为一个数组A和一个整数k,找到数组中 所有的数值对pairs(i,j),其中A[i]和A[j]之间差的绝对值是k.比如[3,1,4,1,5],k=2,ouput=2,这样的差值对是(1,3)和(3,5),其中1虽然在数组中出现过2次,但是只算一次.(题目:…
