public class KboatPattern
{
    public static void main(String args[]) {
        for (int i = 1; i <= 4; i++) {
            int t;
            if (i % 2 == 0)
                t = 1;
            else
                t = 0;
                
            for (int j = 1; j <= 4; j++) {
                System.out.print(t + " ");
                if (t == 1)
                    t = 0;
                else
                    t = 1;
            }
            System.out.println();
