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)

L -> D
X -> Q
V -> U
Q -> F
A -> O
H -> Z
Y -> B
B -> K
O -> B
Z -> A
X -> A
W -> F
R -> Q
P -> W
Q -> Y
A -> K
H -> G
B -> C
J -> O
C -> D
P -> H
E -> S
K -> T
W -> O
I -> N
M -> G
W -> X
G -> H
I -> D
N -> V
F -> I
S -> M
Y -> R
C -> Y
X -> L
T -> G
K -> E
D -> T
J -> Q
P -> G
M -> J
U -> P
