链接:https://leetcode-cn.com/problems/k-diff-pairs-in-an-array/description/ Q: 给定一个整数数组和一个整数k, 你需要在数组里找到不同的k-diff数对。这里将k-diff数对定义为一个整数对 (i, j), 其中 i 和 j 都是数组中的数字,且两数之差的绝对值是k. 示例 1: 思路:k小于0 返回0
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…
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...
(题目:https://leetcode.com/problems/k-diff-pairs-in-an-array/#/description) 思路:把数组中的元素放到map中,key是数组中的值,value是该值在数组中出现的次数。构建好map之后,遍历数组,看看a[i]+k这个值在数组中是否存在。 答案:https://github.com/honpey/codebox/blob/master/leetcode/array/p532.cp...
算法(1)K-diff Pairs in an Array 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 ...
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 inte
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. ...
Can you solve this real interview question? K-diff Pairs in an Array - Given an array of integers nums and an integer k, return the number of unique k-diff pairs in the array. A k-diff pair is an integer pair (nums[i], nums[j]), where the following are
LeetCode-K-diff Pairs in an Array Description: 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 ...
https://leetcode-cn.com/problems/k-diff-pairs-in-an-array/submissions/ 我的答案 可以点击到的最佳答案 所以他这里比我快的点就是他的collections.counter(nums) 用这个可以直接得到一个哈希表所以后面的调用就是count.items()...532. 数组中的K-diff数对 题目原文 给定一个整数数组和一个整数 k, 你需...
