Problem
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 = 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
