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: 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. |

- Create point object that contains x, y co-ordinates and distance from origin.
- Keep adding points to max heap. Custom comparator that uses distance (inside the point object) as key.
- Make sure size of heap does not go higher than K
- In the end, the K points in the heap are your solution
- Since size of heap capped at k, Time complexity nlogK Time complexity logK
