You are developing a system to help the staff of a football/soccer club's web site report on matches. Data is received from a variety of sources and piped into a single stream after being cleaned up.

1. Output descriptions of the players based on their shirt number

The team only ever plays a 4-3-3 formation and has never agreed with the 1965 change to the rules allowing for substitutions, never mind enlarged squads.

The player descriptions are as follows:

1 -> "goalie"
2 -> "left back"
3 & 4 "center back"
5 -> "right back"
6, 7 & 8 -> "midfielder"
9 -> "left wing"
10 -> "striker"
11 -> "right wing"

Implement the static PlayAnalyzer.AnalyzeOnField() method to output a player description based on their shirt number.

PlayAnalyzer.AnalyzeOnField(10);
// => "striker"

2. Raise an alert if an unknown shirt number is encountered.

Modify the PlayAnalyzer.AnalyzeOnField() method to throw an ArgumentException when a shirt number outside the range 1-11 is processed.

3. Extend the coverage to include off field activity

Implement the PlayAnalyzer.AnalyzeOffField() method to output description of activities and characters around the field of play.

You receive a stream of data that has been cleaned. Your task is to analyse it and output appropriate text to help the journalists.

The data comprises:

• shirt numbers (any int) -> text as per on field analysis
• free form text (any string) -> the text unchanged
• incidents in play (any subclass of the type Incident) -> "Injury", "Foul" etc.
• opposing managers (objects of type Manager) -> "the manager"

PlayAnalyzer.AnalyzeOffField(new Injury());
// => "A player is injured. Medics are on the field."
PlayAnalyzer.AnalyzeOffField(new Manager());
// => "the manager"

4. Where the manager has a name available we want that output instead of "the manager"

Modify the PlayAnalyzer.AnalyzeOffField() method to output any name such as "Jürgen Klopp" if there is one. If there is no name then the Manager.Name property is guaranteed to be an empty string rather than null.

PlayAnalyzer.AnalyzeOffField(new Manager("José Mário dos Santos Mourinho Félix", string.Empty))
// => "José Mário dos Santos Mourinho Félix"
