C :

#include <stdio.h>
 
int main()
{
    int a;
    while(scanf("%d",&a) != EOF)
 {
 if (a==1)
   {
    printf("1/27\n");
   }
 else if (a==0) 
     printf("1\n");	
 
  }
    return 0;
}

C++ :

#include <iostream>
#include <string>

using namespace std;

int main()
{
  int n ;
  string answer;
 
  while(scanf("%d",&n) != EOF)

    {
      answer = "1";  
	  cout<<answer<<endl;
    }
	
  }

}

Java :

else if (a==0){
