Solution: Contains Duplicate II
Understand how to apply the sliding window technique to determine if an array contains duplicates within a range of k indices. This lesson guides you through maintaining a window using a set to track elements, ensuring efficient O(n) time complexity and optimized space. Practice implementing this approach to confidently solve similar 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.
