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. WebCountry of origin.

WebAug 21, 2024 · But this is a contradiction since, by construction, all of the accepting states in the new DFA have a path to an accepting state in the original DFA. Therefore, our assumption was wrong and it is the case that every string accepted by the new DFA is a prefix. Part #2: Every prefix of every string in the original language is accepted by the … WebJan 22, 2024 · Step-1: When you divide a number ω by n then reminder can be either 0, 1, ..., (n - 2) or (n - 1). If remainder is 0 that means ω is divisible by n otherwise not. So, in my DFA there will be a state q r that would be …
