Given an integer array nums and an integer k, return true if there are two distinct indices i and j in the array such that nums[i] == nums[j] and abs(i - j) <= k.

  Example 1:

Input: nums = [1,2,3,1], k = 3 Output: true

Example 2:

Input: nums = [1,0,1,1], k = 1 Output: true

Example 3:

Input: nums = [1,2,3,1,2,3], k = 2 Output: false

  Constraints:

1 <= nums.length <= 10⁵
-10⁹ <= nums[i] <= 10⁹
0 <= k <= 10⁵
