Problem Description

Your objective for this question is to develop a program which will generate a fibbonacci number. The fibbonacci function is defined as such:

f(0) = 0
f(1) = 1
f(n) = f(n-1) + f(n-2)

Your program should be able to handle values of n in the range 0 to 50.

 

Input

Each test case consists of one integer n in a single line where 0≤n≤50. The input is terminated by -1.

 

Output

Print out the answer in a single line for each test case.

 

Sample Input

345-1

 

Sample Output

235

#include<stdio.h>

main()
{
    __int64 x[57];
    int i,j,n;
    x[0]=0;
    x[1]=1;
    for(i=2;i<52;i++) 
    x[i]=x[i-1]+x[i-2];
    while(scanf("%d",&n)&&n!=-1)
        {
              printf("%I64d\n",x[n]);                  
                                }
         return 0;                        
      }
