Is test 7 valid?

Posted by Ionel Corneliu Gog 11 Feb 2006 14:47

Please check test 7. I submitted 8 times and I can pass it. I read with gets,fgets.. I think it doesn't have EOLN('\n').

No, it has (-)

That's crappy. If you read like this: scanf("%d%d\n",&n,&m)... it doesn't work and if you read like this scanf("%d%d",&n,&m);gets(line);.. is working.. Can explain me why is this difference?

About test generation (-)

All the tests:
1) were typed in Windows Notepad manually
or
2) were generated by Delphi program via Writeln() procedure

Input is correct. It is the problem of C++ if the code works wrong (-)

Is "scanf( "\n" );" == "gets( line );"???
Why not?

I've not very much exp. in C, but see this bug first time. Maybe, it would be better to read by streams?

completely not.

it is NOT a bug, but a TRICKY case

Posted by Safe Bird 12 Feb 2006 14:41

what is more, if i remove"if (feof(Fin)) break;" i will get TLE on 17!! i think case17 must be wrong...
