We all know that 1+2+…+n=(1+n)*n/2;Gauss worked it out when he was a child!
And we also know the famous number sequence 1,1,2,3,5,8,13… named Fibonacci sequence.(F(1)=F(2)=1;when n>2,F(n)=F(n-1)+F(n-2);)
If we put them togather,what thing will happen?
The input will consist of a series of integers N, one integer per line.Process to end of file.(0<N<1000000000)
For each case,calculate the sum of the Fibonacci numbers who’s sequence number is not bigger than N.Since it can be very huge,you should onle output the last eight digits,do not output leading zeros(if the answer is 02007729,just output 2007729).
20 Hint: 1+1+2+3+5+8=20
