Description
The New Fibonacci numbers (0,1,2,3,6,11,20,37,68,...) are defined by the recurrence:F(0) = 0; F(1) = 1; F(2) = 2;
F(n) = F(n-1) + F(n-2) + F(n-3) for all n>2
Write a program to calculate the New Fibonacci numbers.
Input
The input is a sequence of integers not more than 36,each on a separate line,specifying which New Fibonacci number to calculate.
Output
Print the New Fibonacci numbers in the format shown in Sample Output.
Sample Input
5
7
11
Sample Output
The New Fibonacci number for 5 is 11
The New Fibonacci number for 7 is 37
The New Fibonacci number for 11 is 423
我的代码:
#include
main()
{
x05long F[37];
x05int i,n;
x05while(scanf("%d",&n)!=EOF)
x05{
x05x05F[0]=0;F[1]=1;F[2]=2;
x05x05for(i=3;i

答案

#include
int main()
{
long F[37];
int i,n;
F[0]=0;F[1]=1;F[2]=2;
for(i=3;i
