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:
nums.length...
