i got WA, but the run time is only 0.006 second

why??

this is part of my code of scan file
int pile[8][52];

while(1)
{
scanf("%d", &pile[0][0]);
if(pile[0][0] == 0)
{
break;
}
else
{
for(i=1;i<52;i++)
{
scanf("%d", &pile[0]);
}
........continue
}
}

How do we know how many cards is dealt for a draw??
The problem does not state this. It says a draw occurs
if you can never win or loss. But how many cards for the output?
(Draw: ???) Theoretically,
it should be 0, because you know the cards in the
deck, but instead it's some >0 number as shown in the
sample input. Can someone clarify this? Thanks in advance.

Nevermind, I get it now. Same state repeated = draw step.

Does anyone have a efficient method?

I use string and functions like sprintf() and strcmp() to memorize all cards, and got AC 0.392s.

but I thknk this method is too slow to detect "state repeated".
