Is this possible in oracle?

Question

Hi guys,
i was just curious whether this is possible to display in oracle like C?
situation is like. I have to code like, it should ask user to enter the number.
and then it should display the result on screen like this.
e.g. if user enters 3 then it should show like..
     1
1     2
1 2 3
1 2
1
i know it's possible in C or C++ very easily. but even if it's not possible in oracle, any logic like keeping the result rows in some table..
regards,
--PD!

How about
SQL>  var x number
SQL>  exec :x := 4
PL/SQL procedure successfully completed.
SQL>  with t1 as (select level l, sys_connect_by_path (level, ' ') triag from dual connect by level <= :x order by 1 asc),
     t2 as (select level l, sys_connect_by_path (level, ' ') triag from dual connect by level <  :x order by 1 desc)
select lpad(' ', :x - l) || triag triag from t1
union all
select lpad(' ', :x - l) || triag triag from t2
TRIAG
