How can this get WA?

Posted by Maigo Akisame (maigoakisame@yahoo.com.cn) 18 Aug 2004 09:41

program ural1230;
begin
writeln('A="?''A="+''"''+"''+A+''"+''"''+";''+A";?''A="''+A+''";''+A');
end.

The PIBAS prog is as follows:

A="?'A="+'"'+"'+A+'"+'"'+";'+A";
?'A="'+A+'";'+A

• Use write instead of writeln. CR/LF characters are not allowed in PIBAS program.
• And your program is not introspective, your output is A="?'A="'+A+'";'+A";?'A="'+A+'";'+A

Thx.AC now.
