Question: Create a method that will perform a division operation (divide by) on the numbers passed to it in two variables (numerator, denominator) and outputs the results. Use a try catch pair to output an error message if the illegal operation of divide through 0 occurs.
Rewrite the productions for each of the following nonterminals as right regular grammars: Identifier, Float. Show the moves made using the DFSA for identifiers in accepting.
In this problem, we consider a very restricted subset of Boolean expressions. Define an operator to be one of the four symbols: ¬, ∧, ∨, and →. Define a variable to be one of the five symbols
Discuss the impact of Moore's law on data center costs on such things as servers and communications equipment. List at least 3 steps or recommendations your data center can take to offset some or all of the effect of Moore's law.
Show that the following identities hold for regular expressions over any alphabet: epsilon + R*R = R*. These should be done by interpreting the regular expressions as languages.
Suppose f is a function that returns the result of reversing the string of symbols given as its input, and g. What ambiguity exists in the statement x?
Devise a Turing machine with input given in unary notation such that the equipments produces the following output, 0 if x is divisible by 4,
Prove that L is not regular. (Be particularly careful if you use the Pumping Theorem. You must choose a w that is actually in L.)
We showed to prove that if L can be identified by DFA then the language left half(L) = {x ∈ ∑*|∃y xy ∈ L and |x| = |y|} is also regular; here |x| means length of x.
Design Turing machine (using Sipser notation) having at least 4 nontrivial (i.e., nonrejecting) states and at least six nontrivial (i.e., not to the rejecting state) transitions.
Describe the difference between a Deterministic Finite Automata and Non-Deterministic Finite Automata. In general, which one is expected to have less number of states ?
Write implememnt finite state machine which recognzes input string according to following rules. First character should be either letter(upper or lower case.)
Show that the language F = {a^i b^j c^k | i, j, k greater than or equal to 0 and if i = 1 then j = k} is not regular. Show, however, that it satisfies the statement of the pumping lemma
