Find K Closest Elements
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|anda < b
Example 1
Input
arr = [1,2,3,4,5], k = 4, x = 3Output
[1,2,3,4]The four integers closest to 3 are 1, 2, 3, and 4, returned in ascending order.
Example 2
Input
arr = [1,1,2,3,4,5], k = 4, x = -1Output
[1,1,2,3]The four integers closest to -1 are 1, 1, 2, and 3, returned in ascending order.
Constraints
- 1 <= k <= arr.length
- 1 <= arr.length <= 10^4
- arr is sorted in ascending order.
- -10^4 <= arr[i], x <= 10^4
