import java.util.*;

public class TwohundthrityoneA {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
int n=sc.nextInt();
int count =0; // to count result
for(int i=0;i<n;i++){
int idcount=0; // for indiviual dicision

        int a = sc.nextInt();
        if(a==1){
            idcount++;
        }

        int b = sc.nextInt();
        if(b==1){
            idcount++ ;
        }

        if(c==1){
            idcount++ ;
        }
        if(idcount>=2){
            count++ ;
        }
      }
     System.out.println(count);

     sc.close();
     }
}

here is my code for this problem hope helps
