Assume we have a mechanical hard drive with the following characteristics: number of surfaces - 2 (this is a double-sided disk, a single read/write arm holds both read write heads)number of tracks per surface - 500number of sectors per track - 20number of bytes per sector - 1024in general, information is stored on a disk not at random but in specific locations that to minimize the time it takes to retrieve that information. using the specifications above, where would you store the information in a 50 kb file on the disk to speed up subsequent access to that information.

Show that there is a language a ⚆{0, 1} â— with the following properties: 1. for all x â a, |x| ≤ 5. 2. no dfa with fewer than 9 states recognizes a. hint: you don’t have to define a explicitly; just show that it has to exist. count the number of languages satisfying (1) and the number of dfas satisfying (2), and argue that there aren’t enough dfas to recognize all those languages. to count the number of languages satisfying (1), think about writing down all the strings of length at most 5, and then to define such a language, you have to make a binary decision for each string about whether to include it in the language or not. how many ways are there to make these choices? to count the number of dfas satisfying (2), consider that a dfa behaves identically even if you rename all the states, so you can assume without loss of generality that any dfa with k states has the state set {q1, q2, . . , qk}. now think about how to count how many ways there are to choose the other four parts of the dfa.
