Two Guys Arguing

King of the nerds – Quick and Dirty Programming Contest Winners

Posted in Uncategorized by benjaminplee on 01.24.10

Winning a vendor sponsored timed programming contest at a three day technical conference (CodeMash**) which you voluntarially traveled to in Northern Ohio in the middle of January is a double edged sword.

One the one side you are the king of the nerds.
On the other side …  you are the king of the nerds.

A few weeks ago Josh Schramm, Kevin Berridge, and I (all past Dayton Flyers and college roomates) took in a great CodeMash conference and decided to enter a StoutSystems sponsored programming SmackDown just for kicks.

We won.  All hail the kings of the nerds.

Granted only ~15 teams entered (from 1 -3 people each) but none the less, we won and only one other team submitted even a failed attempt before our winning one.

Josh posted our solution in Ruby to GitHub and I have since cleaned it up a bit, added the original rules, a C# & Linq solution Kevin did while we were there and a new one of my own making in Ruby.

I am planning to write the solution in a few different languages and designs.  If anyone else has an entry or can suggest a way to make the Ruby variant any cleaner or more idiomatic … please leave me a comment or fork my repo on GitHub.

Latest Ruby variation:

lines = []'../input.txt').each { |line| lines << line }

lines = lines[1..lines.size].
              map     { |line| line.split("\t") }.
              each    { |line| line[1] = line[1].gsub(/[^a-zA-Z]/, '').reverse }.
              reject  { |line| line[1].to_s.empty? }.
              sort    { |x, y| (x[1] <=> y[1]) == 0 ? (x[5].to_f <=> y[5].to_f) : (x[1] <=> y[1]) }.
              collect { |line| line.join("\t") }.
              insert(0, lines[0])"output.txt", 'w') { |f| f.write(lines) }

** CodeMash was an absolute blast.  Great sessions, good people, nice venue, and rockin’ live music.
