public class KboatPattern
{
    public void displayPattern() {
        int a = 1, b = 0;
        for (int i = 1; i <= 5; i++) {
            for (int j = 1; j <= i; j++) {
                if (j % 2 == 0)
                    System.out.print(b + " ");
                else
                    System.out.print(a + " ");
            }
