The Qualification Round of the
Google Code Jam 2019 starts in 5 hours! The round lasts 27 hours, so there should be enough time to gather the needed 30 points.
Perl used to be supported in the Code Jam, but last year, the support was dropped. The great news is Perl support is back! Enjoy rather fresh 5.24.1. See you in the scoreboard!
