'K' Closest Points to the Origin (easy)

Problem Statement

Given an array of points in a 2D plane, find ‘K’ closest points to the origin.

Example 1:

Input: points = [[1,2],[1,3]], K = 1
Output: [[1,2]]
Explanation: The Euclidean distance between (1, 2) and the origin is sqrt(5).
The Euclidean distance between (1, 3) and the origin is sqrt(10).
Since sqrt(5) < sqrt(10), therefore (1, 2) is closer to the origin.

Example 2:

Input: point = [[1, 3], [3, 4], [2, -1]], K = 2
Output: [[1, 3], [2, -1]]

Constraints:

  • 1 <= k <= points.length <= 10<sup>4</sup>
  • -10<sup>4</sup> <= x<sub>i</sub>, y<sub>i</sub> <= 10<sup>4</sup>
