![]() ![]() ![]() ![]() ![]() ![]() ![]() | The "+" mean match one or more of the previous element (in this case one or more letters). Without the "+" the pattern will only match a single letter between the slashes. With the "+" it will match one or more letters between the slashes. You don't need it after the [0-9] since you only expect a single digit.
