Are the following languages regular languages or not ? Justify your answer with a proof.

? = {? | ? represents an integer strictly greater than 2020}, on alphabet Σ = {0,…,9}.
? = {? | |?|_a > |?|_b} on alphabet Σ = {a,b}
? = {? | ? is the code of a LOOP program syntactically correct }
? = {0²^?| ? ∈ ℕ} sur alphabet Σ = {0}.

Determine whether or not the following languages are regular. If the language is regular then give an NFA or regular expression for the language. Otherwise, use the pumping lemma for regular languages or closure properties to prove the language is not regular. 1) L = { 0 n1 k : k ≤ n ≤ 2k} 2) L = { 0 n1 k : n > 0, k > 0 } È { 1 k0 n : k > 0, n...

Prove that the following two statements are not logically equivalent. In your proof, completely justify your answer. (a) A real number is less than 1 only if its reciprocal is greater than 1. (b) Having a reciprocal greater than 1 is a sufficient condition for a real number to be less than 1. Proof: #2. Prove that the following is a valid argument: All real numbers have nonnegative squares. The number i has a negative square. Therefore, the...

Prove whether the following are regular (include the file) or not regular (attach a proof). The alphabet is {0, 1}. 1. The set of strings that start with N 0's which are directly followed by 2N 1's. 2. The set of strings start with two 0's, followed by N 1's, followed by N 1's and end with three 0's. 3. The set of strings where every substring of length 5 has more 0's than 1's. Strings less than length five...

This project is intended to increase your understanding of languages and grammars. In a regular grammar (RG), all production rules must have one of the following forms: Ni = t1t2t3...tkNj Ni = t1t2t3...tk where ti denotes a terminal (alphabet symbol), and Nj and Nj denote nonterminals. Any language defined by a regular grammar is a regular language. Regular languages can also be defined by finite automata, transition graphs, and regular expressions. More complex grammars, such as context-free grammars (CFG),...
