trial -- subway transfer, -- subway Transfer
[Problem]
Description: two subway lines are known, where A is the ring line and B is the east-west line. The lines are bidirectional. The names of the sites are as follows, and the interchange points of the two lines are represented by T1 and T2. Write a program, enter the names of the two sites at will, and output the minimum number of stations that need to pass by subway (including the input start and end points, and the transfer site is calculated only once ).
Subway Line A passes through the station: A1 A2 A3 A4 A5 A6 A7 A8 A9 T1 A10 A11 A12 A13 T2 A14 A15 A16 A17 A18
Subway Line B (straight line) goes through the station: B1 B2 B3 B4 B5 T1 B6 B7 B8 B9 B10 T2 B11 B12 B13 B14 B15 input: enter two different station names output: output the least number of stations passed, with the input start point and end point, the transfer site only calculates the input sample once: A1 A3 output sample: 3

to Vv and subway station
Bus Route: 36 → central ring road, about 19.0 km
1. Take road 36 from and go through 12 stations to the East Site of xili Hospital
2. About 290 walk, arrive at xili station, take the ring in the middle of the line, pass through 6 stations, and arrive at Wuhe station subway station to have no fear of damage on the boarding Board
Which of the following is the closest connection between the subway station and the subway station to the station? Urgent
Sakada can take 321 to the base at sakada.
You can also take 391 or 335 to
The subway does not directly reach .
Hope to help you.
