You haven't considered that the problem is in multiple input format, right?
Please read http://acm.uva.es/problemset/minput.html

It has stated to be a multiple input problem~

Note the blue checkmark beside the problem number in the volume contents.

Can some one tell me why it is W.A??

#include<iostream.h>

int main()
{

unsigned long a,f;

while(cin>>a>>f)
{
if(a<=9)
{
for(unsigned long i=1;i<=f;i++)
{
unsigned long j;
for(j=1;j<=a;j++)
{
for(unsigned long k=1;k<=j;k++)
cout<<j;
cout<<"\n";
}
for(unsigned long l=j-2;l>=1;l--)
{
for(unsigned long k=1;k<=l;k++)
cout<<l;
cout<<"\n";
}
if(i!=f)cout<<"\n";
}
}
}
return 0;
}

What's with Multiple Input?

Post by ec3_limz » Sat Jun 29, 2002 6:20 pm

I myself have submitted the same problem over and over again. W. A. all the time.

Um, Picard, I do not actually see why it is wrong answer. The question did not say that then number of test cases will be more than one. Is there anything special about questions having multiple input?

Did you note that the *tick mark* beside the problem number in the problems contents is blue in colour? It means the problem is of multiple input.

The format of multiple input question can be referred as http://acm.uva.es/problemset/minput.html, as Picard said.

Take an extra input for case number though it is not
said to take in the problem.
Wish you good luck.
