Tally the results of a small football competition.
Based on an input file containing which team played against which and what the outcome was, create a file with a table like this:
Team | MP | W | D | L | P
Devastating Donkeys | 3 | 2 | 1 | 0 | 7
Allegoric Alaskans | 3 | 2 | 0 | 1 | 6
Blithering Badgers | 3 | 1 | 0 | 2 | 3
Courageous Californians | 3 | 0 | 1 | 2 | 1
What do those abbreviations mean?
- MP: Matches Played
- W: Matches Won
- D: Matches Drawn (Tied)
- L: Matches Lost
- P: Points
A win earns a team 3 points. A draw earns 1. A loss earns 0.
The outcome should be ordered by points, descending. In case of a tie, teams are ordered alphabetically.

Your tallying program will receive input that looks like:

Devastating Donkeys;Allegoric Alaskans;win
Courageous Californians;Blithering Badgers;loss
Blithering Badgers;Devastating Donkeys;loss
