WebBut it can be the empty set, in which case the NFA aborts its operation. As in the case of DFA the accepting states are used to distinguish sequences of inputs given to the finite automaton. If the finite automaton is in an accepting state when the input ends i.e. ceases to come, the sequence of input symbols given to the finite automaton is ... WebMar 6, 2016 · 5. The only requirement is that any symbol at an odd position must be 1. There is no requirement for a particular number of symbols, and specifically not that there be at least one. Therefore, a DFA with an initial state where 0 leads to a rejection state and where 1 leads to a second state which accepts either symbol and returns to the start ... rbans effort score
