Problematic Problem Setters

Limits: 2s, 1.0 GB

A new national level contest will be held next month. So chief judge asked some problem setters to set the problem and provide some easy problems. These problem setters live in a city called “Bazingapore”, where they have a very good metro rail system. This metro rail system consists of MRT stations. MRT stations are connected with other MRT stations by rail tracks on which train travels both ways. And obviously, these rail tracks don’t create any kind of loops (what’s the point, huh?).
