Question

Second DFA needs to take any lowercase string and check if it contains your first name. The
string can contain any number of characters before and after your name. As long as the string
contains your first name it needs to be accepted.

Expert Solution
Step 1

You must use Prolog to implement two DFAs for this assignment. 1. DFA must first examine a number digit by digit, determine whether it is divisible by 7, then accept it. You will need 7 states (0,1,2,3,4,5,6) and the 10 conceivable digits for your alphabet to accomplish this.

Explanation
For this step, please refer to the solution.

 

Write a DFA Machine programme that accepts a list of all strings over w (a, b)* that contain "aba" as a substring, given a binary string S.

Examples:

Put 1: Addis Ababa

Results: Accepted

Reason: "ababa" is made up of "aba"

Enter 2: abbbb

Results: Rejected

Reason: "abbbb" does not include "aba."
