Has anyone tried pset1 hacker edition "bad credit"? if so, do you know if it should be solved using bitwise operations? I know how to solve it with normal operations but was thinking maybe it's intended to be solved with bitwise. And I'm quite clueless as how to do that.
I can't seem to find the problem set online. Could you post a link to the problem, or, for that matter, to all of the problem sets?
