        int row,col;
        for(row=1;row<=4;row++){
            for(col=4;col>=row;col--) printf(" ");
                for(col=1;col<=2*row-1;col++)printf("*",col);
            printf("\n");
        }
        for(row=4-1;row>=1;row--){
          for(col=4;col>=row;col--) printf(" ");
            for(col=1;col<=2*row-1;col++)printf("*",col);
            printf("\n");
        }
