Explore the sliding window pattern to determine if two distinct indices in an array have equal values with an index difference no greater than k. This lesson helps you understand the problem constraints, develop a clear problem-solving approach, and implement the solution effectively using the sliding window method.

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.
Constraints:
