Discussion of Problem 1522. Factory

Evaluator requires a trailing space

Posted by Bruce Merry 18 Feb 2007 22:50

I carefully wrote my solution to not put any extraneous spaces at the end of the second line and it came back WA #1 every time during the contest. If I now put a space at the end of the line, it comes back as WA #12.

I tried not to add a space at the end of the second line, but AC anyway. There is no such problem (-)

I've put the code I submitted at

http://people.cs.uct.ac.za/~bmerry/a1.cpp

and

http://people.cs.uct.ac.za/~bmerry/a12.cpp

The only difference is that the second puts out a trailing space, the first does not. The first gets WA #1 while the second gets WA #12.

That's because of line printf("%lld", ...). It should look like printf("%I64d", ...). Read C++ FAQ about using 64-bit types:

Argh! Eight years later and we still don't have C99-compliant compilers.

I now get WA #18 but presumably that is a different issue.

??? again. Confusing that the order of the threads changes if you post a solution in the wrong thread, and then want to correct it by going to the other thread. :)
