CS2121 lab exercise 1 part a8 - hint

You need to find anything recognised by the pattern for a1, or by the pattern for a2, or by the pattern for a3, etc. by combining all those patterns together into one big pattern.

You need to think carefully about how you glue them together. If you just concatenate them, you will be looking for lines that contain an apostrophe, followed by a decimal digit, followed by an upper-case letter, etc.

Try thinking about the problem again. Start by thinking about what you want to achieve and how you might go about achieving it, even if you don't know exactly how to write it down.

If you are still stuck, have a look at the hint for part a2

If, when you have created your one big pattern, it doesn't seem to be working correctly, I have one final hint.
