Question 1 - Regular Expressions Find regular expressions that define the following languages: 1. All even-length strings over the alphabet {a,b}. 2. All strings over the alphabet {a,b} with odd numbers of a's. 3. All strings over the alphabet {a,b} with even numbers of b’s. 4. All strings over the alphabet {a,b} that start and end with different symbols. 5. All strings over the alphabet {a, b} that do not contain the substring aab and end with bb.
(a, b): 3. Construct (draw) finite automata for the following regular expressions over the alphabet ? (b) a'b
2. Properties of the following: (a) Regular languages (b) Context-free languages (c) Regular expressions (d) Non-deterministic finite automaton (e) Turing-recognizable and Turing-decidable languages (f) A <m B and what we can then determine (g) A <p B and what we can then determine (h) NP-hard and NP-complete.
Give regular expressions describing each of the following regular languages over Σ = {0,1}: {w : |w| = 3} (PLEASE SHOW WORK)
Give regular expressions describing each of the following regular languages over Σ = {0,1}: {w : w begins and ends with the same symbols} show work!
Automata Prove that regular languages are closed under difference, using an indirect proof (leveraging the closure of other set operators).
