Given an array of integers and an integer k, find out whether there are two distinct
indices i and j in the array such that nums[i] = nums[j] and the absolute
difference between i and j is at most 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
Difficulty:
Easy
Lock:
