Bonus assignment: How to test/find out if two regular expressions are equal with the help of the computer? Problem. We have two regular expressions. What tool (e.g. java library, online service) can be used to answer the question "Are these regular expressions equal?". Maybe, the way to go, would be to provide a bunch of strings and checking automatically (with a computer program), if they all belong to a regular set corresponding to the given regular expression. If you find a solution to this problem: - explain what tool you will use and how to use it. Please be very precise, so that it is possible to follow your directions and get things done. The easiest way for you to explain the solution to the problem, may be to record a tutorial (e.g. with OBS).
