We want you to create a command-line application that will calculate the ranking table for a soccer league.
The input and output will be text. Your solution should parse the provided
sample-input.txt file via stdin (pipe or redirect) or by parsing a file passed
by name on the command line. Your solution should output the correct result via
stdout to the console.
The input contains results of games, one per line. See sample-input.txt for
details. The output should be ordered from most to least points and exactly
match the contents of expected-output.txt.
You can expect that the input will be well-formed. There is no need to add special handling for malformed input files.
In this league, a draw (tie) is worth 1 point and a win is worth 3 points. A loss is worth 0 points. If two or more teams have the same number of points, they should have the same rank and be printed in alphabetical order (as in the tie for 3rd place in the sample data).
This should be implemented in Ruby.
Your solution should be able to be run (and if applicable, built) from the command line. Please include appropriate scripts and instructions for running your application and your tests.
If you use other libraries installed by a common package manager (rubygems/bundler, npm, pip, gradle), it is not necessary to commit the installed packages.
We write automated tests and we would like you to do so as well.
We appreciate well factored, object-oriented or functional designs.
Please document any steps necessary to run your solution and your tests.
This will be run in a unix-ish environment (OS X). If you choose to use a compiled language, please keep this in mind. (Dependency on Xcode is acceptable for objective-c solutions) Please use platform-agnostic constructs where possible (line-endings and file-path-separators are two problematic areas).
