문제

송도에 사는 상근이와 친구들은 송도에서 열리는 펜타포트 락 페스티벌에 가려고 한다. 올해는 맥주를 마시면서 걸어가기로 했다. 출발은 상근이네 집에서 하고, 맥주 한 박스를 들고 출발한다. 맥주 한 박스에는 맥주가 20개 들어있다. 목이 마르면 안되기 때문에 50미터에 한 병씩 마시려고 한다. 즉, 50미터를 가려면 그 직전에 맥주 한 병을 마셔야 한다.

상근이의 집에서 페스티벌이 열리는 곳은 매우 먼 거리이다. 따라서, 맥주를 더 구매해야 할 수도 있다. 미리 인터넷으로 조사를 해보니 다행히도 맥주를 파는 편의점이 있다. 편의점에 들렸을 때, 빈 병은 버리고 새 맥주 병을 살 수 있다. 하지만, 박스에 들어있는 맥주는 20병을 넘을 수 없다. 편의점을 나선 직후에도 50미터를 가기 전에 맥주 한 병을 마셔야 한다.

편의점, 상근이네 집, 펜타포트 락 페스티벌의 좌표가 주어진다. 상근이와 친구들이 행복하게 페스티벌에 도착할 수 있는지 구하는 프로그램을 작성하시오.

입력

첫째 줄에 테스트 케이스의 개수 t가 주어진다. (t ≤ 50)

각 테스트 케이스의 첫째 줄에는 맥주를 파는 편의점의 개수 n이 주어진다. (0 ≤ n ≤ 100).

다음 n+2개 줄에는 상근이네 집, 편의점, 펜타포트 락 페스티벌 좌표가 주어진다. 각 좌표는 두 정수 x와 y로 이루어져 있다. (두 값 모두 미터, -32768 ≤ x, y ≤ 32767)

송도는 직사각형 모양으로 생긴 도시이다. 두 좌표 사이의 거리는 x 좌표의 차이 + y 좌표의 차이 이다. (맨해튼 거리)

출력

각 테스트 케이스에 대해서 상근이와 친구들이 행복하게 페스티벌에 갈 수 있으면 "happy", 중간에 맥주가 바닥나서 더 이동할 수 없으면 "sad"를 출력한다.
