Yes, the part A is over. You can verify your solution in the "Archive" part of the Code Jam site and you can post it wherever else you like. The round isn't over, there'll be parts B and C running in different time slots so people from other time zones can participate easily. The following rounds will only have one part.
map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]
