Solution: Contains Duplicate II
Explore how to efficiently detect duplicates within a given range in an integer array using the sliding window technique. This lesson helps you implement a set-based sliding window solution with O(n) time complexity to determine if any two elements have equal values within k indices apart, providing a practical approach to coding interview problems.

Statement
You are given an integer array, nums, and an integer k. Determine whether two distinct indices, i and j, are in the array, such that nums[i] == nums[j] and the absolute difference between i and j is at most k. Return TRUE if such indices exist; otherwise, return FALSE.
