I had first briefly considered a SQL solution, but it didn't immediately come to mind, and the PL/SQL recursive solution was pretty straightforward, so, I went that direction. I wasn't really too concerned about expense, in this case....;-) I don't see too many practical applications. ;-) -Mark -----Original Message----- From: Vladimir Begun [mailto:[EMAIL PROTECTED] Sent: Mon 12/8/2003 8:19 PM To: Multiple recipients of list ORACLE-L Cc: Subject: Re: A brief detour....;-) Bobak, Mark wrote: > Here it is: [...] > This concludes this public service announcement.

SET VERIFY OFF PAGES 200 DEFINE disks=7 REM Please do not use all_objects :) DEFINE big_table=all_objects COLUMN "Implementation Plan" FORMAT A20 SPOOL hanoi_solution.txt SELECT 'Move it from ' || TO_CHAR(MOD(BITAND(ROWNUM, ROWNUM - 1), 3) + 1) || ' to ' || TO_CHAR(MOD(-BITAND(-ROWNUM - 1, -ROWNUM), 3) + 1) AS "Implementation Plan" FROM &&big_table WHERE ROWNUM < POWER(2, &&disks) AND &&disks < 8 / SPOOL OFF Should work correctly.
