Fix a finite alphabet
WebFix a finite alphabet Σ = {a, b} and define for a string w = σ 1 σ 2 · · · over Σ the operation fifth(w) = σ 5 σ 10 σ 15 · · ·. In words, this operation extracts all characters at positions divisible by 5. We can naturally extend this operation to languages: if L is a language, … WebQuestion: Let alphabet sigma = {a, b, c}. Consider the following languages over sigma such that: L_fs is a finite state language L_ww = {ww w sigma* } (as shown in class, this is not a finite state language) L_nfs = {a^nca^n n greaterthanorequalto 0} (also not a finite state language) Answer each question below about the given combinations of languages.

WebAlphabet (formal languages) In formal language theory, an alphabet is a non-empty set of symbols / glyphs, typically thought of as representing letters, characters, or digits [1] but among other possibilities the "symbols" could also be a set of phonemes (sound units).

WebAlphabet is defined as a non empty finite set or nonempty set of symbols. The members of alphabet are the symbols of the alphabet. We use capital Greek letter Σ to designate the alphabets and Γ (pronounced as gamma) to designate the typewriter font for symbols.
