Re^4: Code Golf: Four is magic

[duelafn]

Doesn't seem to work right -- ($1&&$x[$1]+7) adds 7 too often and !!$& has issues with "000".

echo 1000024 | perl duelafn.pl

Update tracked doiwn more details of the bugs.

I did miss some things there. You should still be able to eliminate the @_ from the pop though.

[duelafn]

Nope, outside a sub it will pop from @ARGV not @_
