K Closest Numbers

Problem

Given a sorted array arr of integers, an integer k, and a target integer target, find the k closest integers to target in arr. Return the k integers in ascending order. If there is a tie, prefer smaller numbers.

Examples:

findKClosestNumbers([1, 2, 3, 4, 5], 4, 3)
// [1, 2, 3, 4]

findKClosestNumbers([2, 4, 5, 6, 9], 3, 6)
// [4, 5, 6]
