Solution: Contains Duplicate II
Understand how to identify duplicates within a limited index range using the sliding window technique. This lesson guides you through maintaining a set to track elements dynamically, allowing you to decide if duplicates exist within k indices. Gain practice implementing and analyzing this O(n) time and O(min(n,k)) space complexity solution for interview success.

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.
