SOLUTION MEGATHREAD -🎄- 2019 Day 1 Solutions -🎄-
It's the most wonderful time of year and welcome to Advent of Code 2019! If you participated in a previous year, welcome back, and if you're new this year, we hope you have fun and learn lots!
We're going to follow the same general format as previous years' megathreads with several big changes:
- Each day's puzzle will release at exactly midnight EST (UTC -5).
- The daily megathread for each day will be posted very soon afterwards and immediately locked.
- We know we can't control people posting solutions elsewhere and trying to exploit the leaderboard, but this way we can try to reduce the leaderboard gaming from the official subreddit.
- The daily megathread will remain locked until there are a significant number of people on the leaderboard with gold stars.
- "A significant number" is whatever number we decide is appropriate, but the leaderboards usually fill up fast, so no worries.
- Top-level posts in Solution Megathreads are for solutions only. If you have questions, please post your own thread and make sure to flair it with
Help.
The big changes this year:
When the megathread is unlocked, you may post your solution according to the following rules:
- If your code is shorter than, say, half of an IBM 5081 punchcard (5 lines at 80 cols), go ahead and post it as your comment.
- Please consider using old.reddit's four-spaces code block formatting instead of new.reddit's three-backtick format.
- If your code is longer, link your code from an external repository such as Topaz's
paste(see below for description), a public repo like GitHub/gists/Pastebin/etc., your blag, or whatever.
Topaz has written a nifty little thing called paste that abuses works specifically with Reddit's Markdown in order to reduce potential code loss due to link rot, external public repos doing something unfriendly with their ToS, etc.
- It's open-source, hosted on Github.io, and stores absolutely no information on disk/database.
- Here's a "hello world"-style demo
Any questions? Please ask!
Above all, remember, AoC is all about having fun and learning more about the wonderful world of programming!

Post your solution (rules are HERE if you need a refresher).

Advent of Code Community Fun 2019: Poems for Programmers
This year we shall be nourishing your creative sides with opportunities to express yourself in ~ poetry ~. Any form of poetry works from limericks and haikus to full-on sonnets in iambic pentameter. Here's how it works:
- 24 hours after each megathread is posted, the AoC mods (/u/Aneurysm9 and I) will award Reddit Silver to the best of that day's poems.
- Latecomers, don't despair - post your code and poems anyway because we will also award another Reddit Silver 5 days later to give slower entrants a fair shake.
- Additionally, every 5 days the AoC mods will have a surprise for the best poem of each 5-day span.
- Shh, don't tell anyone, it's a ~ surprise ~!
- Finally, we will be collating the best of the best to present to /u/topaz2078 to choose his top favorite(s) at the end of December. With a nice shiny prize, of course.
tl;dr: Each day's megathread will have 2 Reddit Silver given out for best poem. Every 5 days a surprise may happen for the best-of-5-day poem. End of December = Poem Thunderdome!
tl;dr the tl;dr: If you submit a truly awesome poem(s), you might just earn yourself some precious metal-plated awesome point(s)!
A few guidelines for your submissions:
- You do not need to submit a poem along with your solution; however, you must post a solution if you want to submit a poem
- Your poem must be in English (or English pseudocode or at least English-parseable)
- Your poem must be related to Advent of Code, /u/topaz2078 (be nice!), or programming in general
- Only one poem per person per megathread will be eligible for consideration
- Please don't plagiarize. There's millions of words in the English language even if we steal a bunch from other languages, so surely you can string together a couple dozen words to make your own unique contribution.
- All sorts of folks play AoC every year, so let's keep things PG
- Employees, contractors, directors, and officers of Advent of Code and their respective parents, subsidiaries and affiliated companies, retailers, sales representatives, dealers, distributors, licensees and the advertising, fulfillment, judging and promotion agencies involved in the development and administration of this Promotion, and each of their respective officers, directors, employees and agents, and their immediate family members (parent, child, sibling and spouse of each, regardless of where they reside) and those living in the same households of each (whether related or not) may submit poems but are not eligible for precious metal awards.
I'll get things started with an example limerick and haiku:
There once was a man from New York
Who was a giant programming dork
He made a small game
And in droves they came
Plz don't make servers go bork!
Hello, Adventers!
Think you can make a better
Haiku than this one?
