Solution: Find K-th Smallest Pair Distance

Explore how to solve the problem of finding the k-th smallest pair distance in a sorted array by combining binary search with the sliding window method. Understand the approach to efficiently count pairs with distances within a given range, and analyze time and space complexity to prepare for coding interviews.

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 < ...
