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)

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