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.

10169  I need Help plzzz (Need code)
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;
}
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;
}
I need help too. Could someone verify my io test ?

Found bug and got AC. The output of previous input should be:

Hi rio send me your code plz
Hi there, can you send me your code for this problem
Your code only takes one case.The input file contains several lines of inputs.
Ouput exactly what is specified. And don't output what is not specified.For each line of input print a single line of output containing a floating point number and an integer. The floatingpoint number indicates the probability that you have picked up two red balls in at least one of your pickups 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.
