Given an integer array, return the k-th smallest distance among all the pairs. The distance of a pair (A, B) is defined as the absolute difference between A and B. Example 1: Input: nums = [1,3,1] k = 1 Output:
【leetcode】719. Find K-th Smallest Pair Distance 题目如下: 解题思路:对于这一类知道上限和下限,求第N位是什么的题目,可以先看看二分查找的方法可不可行。首先对nums进行排序,很显然任意两个元素距离绝对值最小是0,最大是nums[-1] - nums[0],所以第N小的距离肯定在 0 ~ (nums[-1] - nums[0]) ...

719. Find K-th Smallest Pair Distance Given an integer array, return the k-th smallest distance among all the pairs. The distance of a pair (A, B) is defined as the absolute difference between A and B. Example 1: Input: nums = [1,3,1] k = 1 Output: 0 Explanation: Here are a...
The distance of a pair of integersaandbis defined as the absolute difference betweenaandb. Given an integer arraynumsand an integerk, returnthekthsmallest distance among all the pairsnums[i]andnums[j]where0 <= i < j < nums.length. ...
Then we need to find out a method to judge whetheransis the Kth distance, the method is like two pointers, the cost time of this step isO(n)O(n). You can see the code below. Code classSolution{public:booljudgeMore(constvector<int>& nums,intmid,intk){intcnt =0, j =0;for(inti...
