You and your friends love to play pen-and-paper role-playing games, but you noticed that it's difficult to get new people to join your group. They often struggle with character creation.

They don't know where to start. To help new players out, you decided to write a small program that will guide them through the process.

1. Welcome the new player

Implement the RPG.CharacterSheet.welcome/0 function. It should print a welcome message, and return :ok.

2. Ask for the character's name

Implement the RPG.CharacterSheet.ask_name/0 function. It should print a question, wait for an answer, and return the answer without leading and trailing whitespace.

3. Ask for the character's class

Implement the RPG.CharacterSheet.ask_class/0 function. It should print a question, wait for an answer, and return the answer without leading and trailing whitespace.

4. Ask for the character's level

Implement the RPG.CharacterSheet.ask_level/0 function. It should print a question, wait for an answer, and return the answer as an integer.

5. Combine previous steps into one

Implement the RPG.CharacterSheet.run/0 function. It should welcome the new player, ask for the character's name, class, and level, and return the character sheet as a map. It should also print the map with the label "Your character".
