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...
K-diff Pairs in an Array 这道题为简单题 题目: 思路: 我的思路:创建字典,遍历列表,如果nums[i] - k存在于字典中,如果存在那就再判断nums[i]是否存在于a[nums[i] - k],如果nums[i]还没有存在字典中,那么就创建键值对,然后把nums[i] - k和nums[i] 的键值分别添加对应的值(nums[i] + k的情况...
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 ...

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 ...
