Pls help me!!
P.S: isn't the first example wrong?

Your program compiles with no errors. I've also tried once to submit the program in C++ and got CE; rewrited in Delphi it got AC. Another program in C++ got WA, in Delphi - AC.
Admins, fix please the bugs!

1. As for CE - you should look through FAQ ( http://acm.timus.ru/faq.aspx ), there is all information you need there.

2. As for WA - there is no difference for the judge system which language you use. Your program on C++ is just wrong. If you are sure it is correct, contact with Vladimir Yakovlev ( you can find his mail on http://acm.timus.ru/author.aspx?id=17757 ).

In this function:

int nr_nead(int j,int or,int i)
{int nr=0,k,t,l;
for(k=j+1;oras[i][k]!=0;k++)
{t=0;
for(l=1;oras[or][l]!=0;l++)
if(oras[i][k]==oras[or][l]) t=1;
if(t==0) nr=1;
}
return nr;}

Identifier "or" is not legal, try any other.

Good Luck!!!

I have succed to make this program, but I have WA at test #13 :( Thank's anyway
