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)

P -> E
S -> Q
L -> U
F -> T

K -> P
F -> O
E -> N
J -> C
U -> H
V -> Z
A -> D
D -> T
H -> N
Q -> B
S -> D
O -> Z
W -> R
H -> F
C -> H
