代码如下

public class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        int a=scanner.nextInt();
        int sum=0;
        while (sum<a*a){
            int m=scanner.nextInt();
            for(int k=0;k<m;k++){
                System.out.print("0");
                if((sum+1)%a==0) System.out.print("\n");
                sum++;
            }
            int n=scanner.nextInt();
            for(int k=0;k<n;k++){

                System.out.print("1");
                if((sum+1)%a==0) System.out.print("\n");
                sum++;
            }
        }
    }
}
