Here is a list of roads between cities.
You need to find the FASTEST way to get from city A to city Z.
Each road is one-way. For instance, A -> B means there's a road from city A to city B, and B -> A means there's a road from city B to city A.


Solution (like this: ACDTVZ)

I -> C

O -> N
P -> Y
Z -> A
O -> K
D -> H
F -> O
L -> B
C -> R
M -> L
J -> C

E -> N
T -> W
I -> X
C -> I
Z -> P
