Problem type

You are studying animals in a forest, and are trying to determine which animals are birds and which are not.

You do this by taking two measurements of each animal -- their height and their weight. For an animal to be a bird, its height needs to be within some range, and its weight needs to be within another range, but you're not sure what the height and weight ranges are. You also know that every animal that satisfies these ranges is a bird.

You have taken some of the animals you have measured and shown them to biologists, and they have told you which are birds and which are not. This has given you some information on what the height and weight ranges for a bird must be. For the remaining animals, your program should determine if they are definitely birds, definitely not birds, or if you don't know from the information you have.

Input

One line containing an integer ~C~ ~(C \leq 20)~, the number of test cases in the input.

For each of the ~C~ test cases:

  • One line containing an integer ~N~ ~(N \leq 1000)~, the number of animals you have shown to the biologists.
  • ~N~ lines, one for each of these animals, each of the format "~H~ ~W~ ~X~", where ~H~ is the height of the animal, ~W~ is the weight of the animal, and ~X~ is either the string "BIRD" or "NOTBIRD". All numbers are positive integers ~\leq 10^6~.
  • One line containing an integer ~M~ ~(\leq 1000)~, the number of animals you have not shown to the biologists.
  • ~M~ lines, one for each of these animals, each of the format "~H~ ~W~", where ~H~ is the height of the animal and ~W~ is the weight of the animal. All numbers are positive integers.

Output

For each of the ~C~ test cases:

  • One line containing the string "Case #X: " where ~X~ is the number of the test case, starting from ~1~.
  • ~M~ lines, each containing one of "BIRD", "NOT BIRD", or "UNKNOWN" (quotes are just for clarity and should not be part of the output).
