WebThis DFA accepts {} because it can go from the initial state to the accepting state (also the initial state) without reading any symbol of the alphabet i.e. by reading an empty string . … WebFeb 17, 2024 · When the DFA is being run, we record the last point in the string where the DFA was in an accepting state. When we eventually either reach the end of the string or a point at which the DFA can no longer advance, we can return a match if we passed through an accepting state; in other words, if we saved an accepting position, which will be the ...

WebApr 12, 2024 · DFA rejects the string in case it terminates in a state that is different from the accepting state. NFA rejects the string in the event of all branches dying or refusing the string. Time needed for executing an input string is less. Time needed for executing an input string is more. All DFA are NFA. Not all NFA are DFA. DFA requires more space.
