WebNov 2, 2024 · Given an expression of non-regular language, but the value of parameter is bounded by some constant, then the language is regular (means it has kind of finite comparison). Example 2 – L = { [Tex]b^n [/Tex] n <= 10 1010 } is regular, because it is upper bounded and thus a finite language. WebLet L be a finite language containing n + 1 strings. Choose any string s ∈L , and let L ′ =L −{s } be simply all of the strings in L except s . We can express L as the union L ′ ⋃{s }. Furthermore, L’ = n and {s} = 1 so by the inductive hypothesis L’ is regular and by the base case {s} is regular.
