C :

#include<stdio.h>
int main(){
	int n;
	while(scanf("%d",&n) != EOF){
			
				if(n%5==1){
			printf("0\n");
			}else if(n%5==2){
			printf("1\n");
			}else if(n%5==3){
			printf("1\n");
			}else if(n%5==4){
			printf("0\n");
			}else if(n%5==0){
			printf("-1\n");
			} 
			
			
}	
		
		


}

C++ :

#include <iostream>
using namespace std;
int main(int argc, char *argv[])
{
	//freopen("test.in","r",stdin);
	//freopen("test.out","w",stdout);
	 int n;
	 while(cin>>n){	
 		n++;
 		if(n%5==1)
 		cout<<-1<<endl;
 		else if(n%5>2)
 		cout<<1<<endl;
 		else
 		cout<<0<<endl;
 	}
	return 0;
