    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

    • <code>1 <= arr.length <= 10<sup>4</sup></code>

    • arr is sorted in ascending order.

    • <code>-10<sup>4</sup><= arri, x <= 10<sup>4</sup></code>
