if A is B's master ans B is C's master, then A is C ' s master.Inputthe input consists of several test cases. For each case, the first line contains-integers, N (members to is tested) and M (relationships to be tested) (2 To make IT simple, we give every one a number (0, 1, 2,..., N-1). We use their numbers instead of their names.Outputfor each test case, print
