Show that there is a language a âťâ {0, 1} ââ with the following properties: 1. for all x â a, |x| ââ°Â¤ 5. 2. no dfa with fewer than 9 states recognizes a. hint: you donââŹâ˘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 arenââŹâ˘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.

Write a full class definition for a class named player , and containing the following members: a data member name of type string .a data member score of type int .a member function called setname that accepts a parameter and assigns it to name . the function returns no value.a member function called setscore that accepts a parameter and assigns it to score . the function returns no value.a member function called getname that accepts no parameters and returns the value of name .a member function called getscore that accepts no parameters and returns the value of score .this is what i have, aparently this is wrong: class player{private: string name; int score; public: void player: : setname (string n){name =n; }void player: : setscore (int s){score = s; }string player: : getname (){return name; }int player: : getscore (){return score; }};
