Valerio is robbing a bank, but an alarm started ringing as he was trying to break into the caveau.

The police is already looking for him and has sent K patrols, indexed from 0 to K-1 to guard the manholes connected to the sewer system.
There are N manholes, indexed from 0 to N-1 and M tunnels connecting pairs of them. Valerio's friend Filippo is waiting for him nearby manhole N-1, if he can reach it, he will escape safely.
Valerio starts from manhole 0 and, every minute, he can choose to move to a manhole adjacent to the one he is in or to stay another minute under the same manhole.
Each police patrol guard L i manholes, indexed from 0 to L i-1. Patrol i is initially guarding manhole H i,0, every minute it moves from manhole H i,j to manhole H i,j+1, after reaching manhole H i,Li-1, it return to manhole H ~i,0 .
