GO Classes Test Series 2024 | Mock GATE | Test 11 | Question: 62
Below you see the transition table of a finite state automaton. The initial state is $0;$ the final state is $4.$ $\emptyset$ denotes the fail state, where no successful transition is possible for the given symbol. Note that when encountering a $b$ in state ... $\mathrm{abbb}^+\mathrm{c}^+\mathrm{c}$ $a b^* b b(c c)^+$

#Regular Languages
For a particular input, a turing machine can ‘hang’ on encountering an infinite loop. Why can’t we say the same for any other machine? i.e A DFA or NFA that follows say a*(b). Will the automaton not ‘hang’ if a string $a^n$ where $n \to$ ∞ is fed to it? Isn’t ‘never accepting but progressing’ the same as hanging?

Convert given DFA to regular expression, I think it's just that 2 is dead state and thus can be eliminated.
