# Game rankings

## Implement a ranking program using the Elo ranking algorithm.

### Given two files:

1. names, where each line has an ID number and a name for said ID

2. matches, where each line contains the ID of the two players of a match and the first one is the winner of said match.

### Implement a program that can read both files and then:

1. Score each player based on the games played

2. Generate a list of players sorted by score, their ranking (position in the list) and their number of wins and losses.

3. Generate a report for each person, showing with whom they played and how they fared.

4. Generate a list of suggested next matches.

### Implementation notes:

1. You can choose how to implement the different functionalities for the program. You may choose to implement it as a command line

parameter (e.g. "./elo names matches show_ranking", "elo names matches show_rank USER_NAME", etc).

2. Try to keep the output format independent of the main application logic (ie design it so that it is possible to add new output formats if

needed
