The game has Q rounds, in each round Tail chooses an positive integer R1 and draw a circle centered at her position with the radius R1. East chooses an positive integer R2 and draw a circle centered at her position with the radius R2.

For each round, print how many islands are included in Tail's circle only and how many islands are included in East's circle only and how many islands are included in both circles.
