Sorry, the judge's output was wrong. It will be fixed soon.

Thankx in advance..

is the the judge's output fixed ?
The problem seems very easy. I checked all my solutions with Mathematica and they are exactly the same. I can not understand how it comes WA.
I assumed that the input '0' is not legal. If it is this my mistake, what should be the output?
Thx in advance for any reply.

I tried it lot of times and i m unable to solve it, here is my code:
void main(void)
{
int n;
cout<<"How many times you pick up ?";
cin>>n;
long double result=1;
double turn=1.0;
for (int i=1;i<=n;i++)
{
result=result * ( (1/turn) * (1/(turn+1)) );
turn++;
}
cout<<result<<endl;
}

Found bug and got AC. The output of previous input should be:
Code: Select all
0.675050 14
0.700373 317
0.703028 5138
0.703295 71322
0.703322 913151
0.703325 11131411

The input file contains several lines of inputs.
Your code only takes one case.
For each line of input print a single line of output containing a floating point number and an integer. The floating-point number indicates the probability that you have picked up two red balls in at least one of your pick-ups and the second integer denotes how many consecutive zeros are there after decimal point in the probability value that all of your pick ups has both balls as red.
Ouput exactly what is specified. And don't output what is not specified.

(Thanks rio ) I tried your input values, now i got write answer, but how to break exponential numbers in normal numbers and how to get number of zeroes after decimal point.
