Solution: Find K-th Smallest Pair Distance

Explore a method to determine the kth smallest pair distance in an integer array by combining sorting with binary search and sliding window techniques. Understand how to count valid pairs and narrow search ranges effectively to solve this problem with an optimal time complexity.

We'll cover the following...

Statement

Given an array of integers nums and an integer k, return the kthk^{th} smallest distance between any pair of integers (nums[i], nums[j]), where 0≤0 \leq i < ...
