Commands: clear (clear stack), dup (duplicate top), swap (swap top two). Example: '3 4 +' returns 7 Args: expression: Space-separated RPN expression (e.g., "3 4 +"). show_stack: Whether to return full stack after evaluation (default: False). Returns: The computed result as a string, or error message if evaluation failed. Example: >>> evaluate("3 4 +") 'Result: 7'
