I am getting WA but I can't find a wrong test case... Any hints?
Also, what is the correct output to:
Code: Select all
A01 0100 0200
#
A01 0099 A01 0098
#
0? 200? I think it is not a cul de sac, so 200 must be correct. Anyway, I tried both approaches and judge gives me WA.
Thanks in advance

Thanks for your help!!! Now I believe that judge is wrong.
I submitted the code of that web and it got AC. But I tested one of the above cases and the answer is not correct, specifically:
Code: Select all
A11 1612 1720
A12 1508 1636
S16 1152 1250
S17 1048 1134
S17 1272 1326
#
S18 1202 S18 1203

The AC program outputs 180. I think it fits to the following race:
But this is not the optimal solution. My WA program outputs 164, corresponding to:
I found other different outputs but my path is always shorter... Am I doing something wrong?
Cheers!
