Regex Golf
One pattern. Two groups. The shortest clean win.
$ regexgolfA regex that matches everything is easy. A regex that knows exactly what to reject is the game.
Read the examples, write a pattern, and test it against group A and group B. Every character counts: beat the known par for a bonus, or use a hint and pay for the help.
The terminal keeps the feedback direct so you can iterate on anchors, classes, alternation, and the smallest expression that tells the right story.
