Solution: Find K-th Smallest Pair Distance

Explore how to efficiently find the k-th smallest pair distance in an integer array by combining sorting, binary search, and the sliding window method. This lesson helps you understand how to apply these techniques together to count valid pairs and optimize time complexity, enabling you to solve distance-based coding problems effectively.

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 < ...
