Maximum clique is the clique that has maximum number of vertex. Input Input contains multiple tests. For each test: The first line has one integer n, the number of vertex. (1 < n <= 50) The following n lines has n 0 or 1 each, indicating whether an edge exists between i (line number) and j (column number). A test with n = 0 signals the end of input. This test should not be processed. Output One number for each test, the number of vertex in maximum clique. Sample Input
