Question No.1
Find the Regular Expression corresponding to the given FA. Show all steps. Mark: 5
[Hint: FA to GTG a GTG to RE.]
Question No.2 Mark: 5
A student walks into a classroom and sees on the blackboard a diagram of a TG with two states that accepts only the string Λ. The student reverses the direction of exactly one edge, leaving all other edges and all labels and all final states (+’s) and start state (-) the same. The new TG accepts the language a*. What was the original TG?
Question No. 3
