Following this transition causes c c to be pushed onto the stack. Any of the 3 symbols a,b,c a,b,c can be \epsilon ϵ.

The language accepted by an automaton is the set of strings it accepts. So, for an automaton to accept a particular language (e.g., { a n b n ∣ n ≥ 1 } ), it must not only accept every string in the language, but also reject every string not in the language. hotpot.ai restore

WebFeb 8, 2016 · You start in the initial state, step through the string character by character, and at each step simply look up the next state. When you are done stepping through the string you simply check if the final state is in the set of accepting states.

This depends on if the pattern defined in the automata is in the input. A finite automaton will consists of a set of states, start state, end state and a set of transitions.
