Problem: Find K Closest Elements

Medium
30 min
Explore how to identify the k closest elements to a target value in a sorted array by applying modified binary search principles. Learn to handle ties by selecting smaller values and ensure the output remains sorted. This lesson prepares you to approach such proximity search problems confidently.

Statement

You are given a sorted array of integers, nums, and two integers, target and k. Your task is to return k number of integers that are close to the target value, target. The integers in the output array should be in a sorted order.

An integer, nums[i], is considered to be closer to target, as compared to nums[j] when |nums[i] - target| << |nums[j] - target|. However, when |nums[i] - target| == |nums[j] - target|, the smaller of the two values is selected.

Constraints:

  • 11 \leq k \leq nums.length
  • 11 \leq nums.length 103\leq 10^3
  • nums is sorted in ascending order.
  • 104-10^4 \leq nums[i], target 104\leq 10^4
