Re: O(log²) and O(1). 8^?.

That's a confused smiley. I resolve to go away and find a good reference on Big-O notation. I seem to recall not having a problem with it when I learnt it 25 or so years ago, but I definately need a refresher course now.

Did I miss something? How do you derived a 8-digit date from an 9-digit number?

I like the bogus days trick though.

Re: (sick minds think alike?)

How dare you imply that I think?

Update: Now why do you suppose someone felt the need to downvote this node?

• Because I didn't understand big-O?
• Because I admitted I didn't understand big-O?
• Because I resolved to re-learn big-O?
• Because I questioned dws?

  (I know it wasn't dws, cos we had further discussion on the subject.)

• Because I like the "bogus days" trick?
• Because I made a joke at my own expense?

You can bet your bottom dollar whomever downvoted it won't have the hutspar (sp?) to explain his or her decision.
