I couldn't pass the review exercise 27 even using the official solution provided. It seems that (\d+)-(?1) also matchs 12-304 and 100-2000. Please fix it, thanks

holy peak this is so good. I've tried so many courses to learn regex, but this course has just made everything click. it takes you through each concept one at a time and gives you a bunch of practice before going on to the next concept. 1000% recommend
