Hope it'll help

Pls check the output for input=6, output should be 1.563.
I also got WA before handling specially this input.

Hi Pochmann !
Would u pls give some hints how to handle the 2nd part,i.e. how to prevent the loops by bool-array. As a beginner, I couldn't find out any other way except linear-checking that would be judged as TimeLimitExceeded.
Thanks in advance.

U should use 'long long' data type. It gives u 8 byte. And change the line :
tmp %= 100
with
tmp %= 100000 ( or, tmp%=1000000)

I suggest u to change a single line as follows:
while ( gets(B) && strlen(B) > 0 )
instead of
while ( gets(B) != NULL )

Hope u'll get it AC...

Ivan, I'm facing some problem! I tried as follows: I generated first 22000 prime numbers & then used the formula:fib(n)=pow((1+sqrt(5))/2,n)/sqrt(5). But the 22000'th prime is about 250000. So fib(n) is so big... Then how I can get the first 9 digits ! Pls tell how it's possible. By the by,I couldn'...

Ivan , Thanks for ur reply. But still I've few problems: first, I know Fib(n)=(pow(a,n)-pow(b,n))/sqrt(5).Here a,b are 2 constants. But it's an approximate value. Then how it could be correct? second, I got it from rank list that Fib(n) and Fib(m) are relative prime if & only if n and m are relative...
