This final project will be worth the same points as 2 programming assignments (200 points). Problem Definition In this assignment, you will be completing the bulletin board you began in PROGRAM 3. We will be adding two major new functionalities: The bulletin board will now be able to handle replies to replies, and will display them indented according to their "level" (e. g. Replies are indented 2 spaces; Replies to Replies 4 spaces; Replies to Replies to Replies 6 spaces; etc.) You will use recursive techniques to display this. The board will now be able to save the entire board (all Message content) to file, and read that file back in; as well as reading in User data from file as you did with the previous bulletin board assignment. You may re-use your code from the previous BBoard assignment (with modifications, of course) - but as always using another student's code will trigger disciplinary action.

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.
