You have a very large square wall and a circular dartboard placed on the wall. You have been challenged to throw darts into the board blindfolded. Darts thrown at the wall are represented as an array of `points`

on a 2D plane.

Return the maximum number of points that are within or lie on **any** circular dartboard of radius `r`

.

**Example 1:**

Input:points = [[-2,0],[2,0],[0,2],[0,-2]], r = 2Output:4Explanation:Circle dartboard with center in (0,0) and radius = 2 contain all points.

**Example 2:**

Input:points = [[-3,0],[3,0],[2,6],[5,4],[0,9],[7,8]], r = 5Output:5Explanation:Circle dartboard with center in (0,4) and radius = 5 contain all points except the point (7,8).

**Example 3:**

Input:points = [[-2,0],[2,0],[0,2],[0,-2]], r = 1Output:1

**Example 4:**

Input:points = [[1,2],[3,5],[1,-1],[2,3],[4,1],[1,3]], r = 2Output:4

**Constraints:**

`1 <= points.length <= 100`

`points[i].length == 2`

`-10^4 <= points[i][0], points[i][1] <= 10^4`

`1 <= r <= 5000`

class Solution {
public int numPoints(int[][] points, int r) {
}
}
