Hints

General

• A map is an associative data structure of key-value pairs.
• Elixir offers many useful Map module functions in the standard library.

1. Define a new high score map

• It should return an empty map.
• Map module functions or literal forms can be useful.

2. Add players to the high score map

• The resulting map should be returned.
• Map module contains functions useful for manipulating maps. One of them puts a value in a map under a given key.

3. Remove players from the score map

• The resulting map should be returned.
• Map module contains functions useful for manipulating maps. One of them deletes a key from a map.

4. Reset a player's score

• The resulting map should be returned with the player's score reset to an initial value.
• Map module contains functions useful for manipulating maps. One of them puts a value in a map under a given key.

5. Update a player's score

• The resulting map should be returned with the player's updated score.
• Map module contains functions useful for manipulating maps. One of them updates a value in a map under a given key.

6. Get a list of players

• Map module contains functions useful for manipulating maps. One of them returns a list of all keys in a map.
