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