658 - Find K Closest Elements.

Medium

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.

An integer a is closer to x than an integer b if:

• |a - x| < |b - x|, or
• |a - x| == |b - x| and a < b

Example 1:

Input: arr = [1,2,3,4,5], k = 4, x = 3

Output: [1,2,3,4]

Example 2:

Input: arr = [1,2,3,4,5], k = 4, x = -1

Output: [1,2,3,4]

Constraints:

• 1 <= k <= arr.length
• 1 <= arr.length <= 104
• arr is sorted in ascending order.
• -104 <= arr[i], x <= 104
