Construct a pda that accepts the language defined by the grammar S → aSSSab | λ .

This has already been answered using software with no explanation. I am not interested in the answer so much. I just want an explanation. or at least a step by step formula.

Draw PDA transition diagram for the following language: The set of strings over the alphabet {x, y} where 2 * (# of x's) = 3 * (#y's) That is, if we let nx be the number of x's and ny be the number of y's, then the strings in these language are those where 2nx = 3ny Try to find a PDA that is as simple and elegant as possible (do not convert from CFG). ------------------------------------------------------------------------------------------------------------------ USE Notation between transition:...

Construct a dfa that accepts strings on {0, 1} if and only if the value of the string, interpreted as a binary representation of an integer, is zero modulo five. For example, 0101 and 1111, representing the integers 5 and 15, respectively, are to be accepted.

Now that you know a bit about BNF's, try writing a grammar (productions) for the "language" of a phone number, which consists of: three digits enclosed in parentheses - the first digit cannot be "0" (zero) followed by three digits - the first digit cannot be "0" (zero) followed by a "-" (dash) followed by four digits So, (757)530-4601 is a valid phone number. All the following numbers are invalidaccording to this grammar: 757-530-4601 (area code is not in parentheses)...

For a grammar G with the productions where G = ( {S, A, B}, {a, b}, S, P ) with productions S --> AB | bbbB, A --> b | Ab, B --> a.. 1.Show that the grammar G is ambiguous. 2.Give language L that is generated by G, L = L(G), in a formal expression (including a regular expression). 3.Can you construct an unambiguous grammar that is equivalent to G? Otherwise, show that G is inherently ambiguous.
