Write a Python program to create a union of sets (A union of two or more sets returns distinct values from both the sets. i.e. no duplicates). Have it so users enter the sets themselves. inputs: set1 = {"squirrel", "dog", "cat", "bird"} set2 = {"nut", "bird", "apple", "squirrel"} output:

I would be interested in further information on the many applications of automata theory.

Question for 2.7 Hi there, I'm having difficulty with this problem, specifically with part C. I'm unsure about the steps to take. Would it be possible for you to provide a visual representation or diagram to assist me with both parts? I would prefer a drawing of the pushdown automaton rather than explanations in text. I'm specifically seeking help with question 2.7 and would appreciate a visual representation of the pushdown automaton. Please ensure that the components are labeled so I can distinguish part C. My request is solely for assistance with question 2.7. However, addressing question 2.6 is necessary to tackle 2.7. Once again, my main focus is on question 2.7. Could you kindly provide a picture illustrating both parts of the pushdown automaton?   2.7 Give informal English descriptions of PDAs for the languages in Exercise 2.6. question 2.6 2.6 Give context-free grammars generating the following languages. c. {w#x | w R is a substring of x for w, x ∈ {0,1} ∗ }

I was wondering if you could clarify the distinction between the Harvard and von Neumann schools of computer architecture. I appreciate it.
