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
