DBSCAN Core Point

Decide whether point i is a DBSCAN core point: it is a core point if at least min_samples points (including itself) lie within Euclidean distance eps of it.

Implement solve(X,i,eps,min_samples=1).

Returns. Return 1 if point i is a core point and 0 otherwise.

Examples

Example 1

Input:

solve([[0.0, 0.0], [0.1, 0.0], [3.0, 3.0]], 0, 0.2, 2)

Output:

1

Example 2

Input:

solve([[0.0, 0.0], [0.1, 0.0], [3.0, 3.0]], 2, 0.2, 2)

Output:

0
