            for(col=1; col<=2*row-1; col++){
                if(col%2==0)  printf("*");
                else printf("%d",row);
            }
            printf("\n");
        }
        for(row=4; row>=1; row--){
            for(col=1; col<=2*row-1; col++){
                if(col%2==0)  printf("*");
                else printf("%d",row);
            }
