Solution: Find K-th Smallest Pair Distance

Explore how to compute the k-th smallest pair distance in an integer array by combining sorting with binary search and the sliding window technique. This lesson teaches you to optimize counting pairs within a distance threshold and understand time-space complexity trade-offs for efficient problem-solving in coding interviews.

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 00 \leq i < ...
