Question

Does anyone know how to do problem 3 in pset 3? The empty string cases for the constrainedMatchPair function is unsolvable.

Answer 1

What code do you have so far? If I've read the problem correctly, this can be done in a single statement (though using some slick python syntax you may not be familiar with). Even doing it longhand though isn't too bad.

Answer 2

Yes, I have been able to solve it using the longhand method. Can you tell us where exactly you are getting stuck?
