CodeX is building a rich text editor for its document tools, and they want to support undo/redo functionality for user input.

Implement a TextEditor class with basic editing and undo/redo support.

public class TextEditor
{
    public void Type(string text);
    public void Delete(int count);
    public void Undo();
    public void Redo();
    public string GetContent();
}

• Only two operations can be undone/redone: Type and Delete.
• Undo reverses the last operation.
• Redo applies the last undone operation.
• Typing or deleting after and undo clears the redo history.
