Трамвайный форум | 18 янв 2013 19:13 | 3 | Could you please check my submissions. The accepted one (I actually copy-pasted it from this forum) gives wrong answer to the following data set: tram (only 4 symbols in input.txt file) The output is "Bus driver". My original solution (#4725054) gives "Tram driver" answer to the mentioned data set, but fails on test #6. Can you please give information what is wrong with this test? Thank you. Last line of input data is always terminated with end of line character (it is the usual rule of Timus Online Judge), so this test is incorrect. Ok, got this. So I assume the problem is on my side.
