1/**
2 * [658] Find K Closest Elements
3 *
4 * Given a sorted integer array arr, two integers k and x, return the k closest integers to x in the array. The result should also be sorted in ascending order.
5 * An integer a is closer to x than an integer b if:
6 * 
7 * 	|a - x| < |b - x|, or
8 * 	|a - x| == |b - x| and a < b
9 * 
10 *  
11 * Example 1:
12 * Input: arr = [1,2,3,4,5], k = 4, x = 3
13 * Output: [1,2,3,4]
14 * Example 2:
15 * Input: arr = [1,2,3,4,5], k = 4, x = -1
16 * Output: [1,2,3,4]
17 *  
18 * Constraints:
19 * 
20 * 	1 <= k <= arr.length
21 * 	1 <= arr.length <= 10^4
22 * 	arr is sorted in ascending order.
23 * 	-10^4 <= arr[i], x <= 10^4
24 *
