Finite automata FA for the language of all those strings starting with a and ending with a in theory of automata

By: Prof. Dr. Fazal Rehman | Last updated: March 3, 2022

Built the finite state automata (FSA) for the language of all those strings starting with a and ending with a but does not contains single a, defined over āˆ‘={a,b}?

Accepted Strings:

Following strings are part of the language and should be accepted by FSA.

Strings = {aa, aba, abba, aaa, aabba, abbaa,…………. }

Rejected Strings:

Following strings are not part of the language and should be rejected by FSA.

Strings = {a, b, Ā ba, bba, abab, Ā baba, babba, abbab,……..….. }
