973 - K Closest Points to Origin\. Medium Given an array of `points` where points[i] = [xi, yi] represents a point on the **X-Y** plane and an integer `k`, return the `k` closest points to the origin `(0, 0)`. The distance between two points on the **X-Y** plane is the Euclidean distance (i.e., √(x1 - x2)2 + (y1 - y2)2). You may return the answer in **any order**. The answer is **guaranteed** to be **unique** (except for the order that it is in). **Example 1:** ![](https://assets.leetcode.com/uploads/2021/03/03/closestplane1.jpg) **Input:** points = \[\[1,3],[-2,2]], k = 1 **Output:** [[-2,2]] **Explanation:** The distance between (1, 3) and the origin is sqrt(10). The distance between (-2, 2) and the origin is sqrt(8). Since sqrt(8) < sqrt(10), (-2, 2) is closer to the origin. We only want the closest k = 1 points from the origin, so the answer is just [[-2,2]]. **Example 2:** **Input:** points = \[\[3,3],[5,-1],[-2,4]], k = 2 **Output:** [[3,3],[-2,4]] **Explanation:** The answer [[-2,4],[3,3]] would also be accepted. **Constraints:** * 1 <= k <= points.length <= 104 * -104 < xi, yi < 104
