Suppose I wanted to hack someone's email, and all I knew about their password was that there were x characters in the password and there were y characters among the 101 on the keyboard that could be in it (for example, if the password consisted exclusively of alphanumeric characters, y = 36). If I had unlimited time to sit down and try to hack it using just those facts and trial and error, what equation would I use to figure the greatest number of attempts I will possibly have to make to finally get it right? Would it be x^y, y^x, x^(xy)? Help a brother out.
