in reply to (Golf) Kaprekar's Process
Aarrrgghhhh!!! I'm going crazy here. I can't seem to figure out why something is working the way it is; could any of you help me? I left all my debugging print statements there so that you can run it yourself and see the same results.
For some reason, the map statement in b() is resulting in that strange "312321,123312" results ... which for the life of me, I can't figure out why.sub b { print 'args=',join(",",@_),"\n"; $,=pop()-pop(); print ", = $,\n"; $x=join'',sort split//,$,; print "x = '$x'\n"; ## the line below doesn't seem to work!! @_=map{scalar reverse($_),$_ } $x; print "\@_ = ",join(",",@_),"\n"; print "\n"; $,==495?0:1+b(@_); } sub c { @a=map{ scalar reverse($_),$_ } pop; print join(",",@a),"\n"; } c(312); b(312); ==== Results when run< ==== 213,312 ## this is c() args=312 ## this is b() , = 312 x = '123' @_ = 312321,123312
I have a feeling it's something stupid, but I can't see it. Can anyone else?
Update: God, I love this place. You write a technical, perl question, one that contains a user-error (such as I did, using $, as a temporary variable (golf, you know)), and you get down voted as much as upvoted. This node of mine has bounced from -1 to 1 so many times my head is spinning. So at what point is a question stupid enough that you shouldn't ask? I seem to remember quite a few people having on their tag lines, and on their tongues, the phrase of "Ask a silly question, be a fool for a minute, don't ask a silly question and be a fool forever.". I guess that doesn't always apply, huh?</rant>
