TDT4205 PS1 1.1 Regex Tester

This website will tell you if the regex you make successfully matches the langauge L.

Recall that L is all non-empty strings over the alphabet {a, b, c} adhering to the following rules:

• The letter a is always followed by either b or c.
• The letter b is always followed by either a or c.
• The letter c is always followed by either c or the end of the string.

The website runs the regex against a few tests, both strings that belong to L, and strings that don't.
