CodeChefRating 2756Open on judge ↗

Chef is very popular, so his friends visit him often. Chef's friend Pesic decided to come visit him in Chefland during one of Pesic's famous world tours, but he got lost along the way and ended up in Queryland. Queryland has a weird structure: it has $N$ cities (numbered $1$ through $N$) and $N-1$ bidirectional roads connecting them in such a way that it is possible to reach any city in Queryland
