Solution: Find K-th Smallest Pair Distance
Explore how to solve the problem of finding the k-th smallest pair distance in an integer array by applying sorting and binary search combined with the sliding window technique. This lesson helps you understand how to efficiently narrow down the search space and count valid pairs using two-pointer traversal, enabling optimal time and space complexity for coding interview problems.

Statement
Given an array of integers nums and an integer k, return the nums[i], nums[j]), where i j num.length.
The distance between a pair of integers,
and , is defined as the absolute difference between them.
