Input is terminated by a line containing five zero\u0027s and is not processed.\r\n\r\n#### Output\r\nFor each test case print \"**Possible**\" (without quotes) if there exists an arithmetic expression as described above that yields **23**. Otherwise print \"**Impossible**\"."}},{"title":"Example","value":{"format":"HTML","content":"\u003ctable class\u003d\u0027vjudge_sample\u0027\u003e\n\u003cthead\u003e\n \u003ctr\u003e\n \u003cth\u003eInput\u003c/th\u003e\n \u003cth\u003eOutput\u003c/th\u003e\n \u003c/tr\u003e\n\u003c/thead\u003e\n\u003ctbody\u003e\n \u003ctr\u003e\n \u003ctd\u003e\u003cpre\u003e1 1 1 1 1\n1 2 3 4 5\n2 3 5 7 11\n0 0 0 0 0\n\u003c/pre\u003e\u003c/td\u003e\n \u003ctd\u003e\u003cpre\u003eImpossible\nPossible\nPossible\n\u003c/pre\u003e\u003c/td\u003e\n \u003c/tr\u003e\n\u003c/tbody\u003e\n\u003c/table\u003e\n"}}]}
