/* In this example, TextEditor uses different ITextState implementations

* to alter how text is formatted based on the current state.

* When the state changes (e.g., to bold or italic), the TypeText method

* formats the text according to the rules defined in the current state.

* This approach cleanly separates the concerns of text formatting from the

* editor logic, making it easy to add new styles or modify existing ones

* without changing the TextEditor class. */

TextEditor editor = new TextEditor();

// Typing in normal state

Console.WriteLine(editor.TypeText("This is normal text."));
