1. Recursively define strings in the following language: A = {0"1"+mom nm >0} Then create a context-free grammar to describe the language.
Give a context free grammar for the language L where L = {a"bam I n>:O and there exists k>-o such that m=2"k+n) 3. Give a nondeterministic pushdown automata that recognizes the set of strings in L from question 3 above. Acceptance should be by accept state. 4. 5 Give a context-free grammar for the set (abc il j or j -k) ie, the set of strings of a's followed by b's followed by c's, such that there are either a...
Write a grammar in Chomsky Normal Form whose language is {w € {a,b}* | w = a ba?bk, j, k >0}. Make sure your grammar is designed with roles for the variables to make the language derived clear.
13.) Write a grammar for the language consisting of strings that have n copies of the letter a followed by one more number of copies of the letter b, where n>0. For example, the strings abb, aaaabbbbb, and aaaaaaaabbbbbbbbb are in the language but a, ab, ba, and aaabb are not. Answer the aaaaaabbbbbbbh are in the languagebr 14.) Draw parse trees for the sentences abb and aabbb, as derived from the grammar of Problem 13. Answer:
What language does the grammar below generate? S rightarrow abS | aA A rightarrow aA | a Select the correct answer. L = {(ab)^n aaa^m: n greaterthanorequalto 0, m greaterthanorequalto 0} L = {(ab)^n a^m: n greaterthanorequalto 0, m greaterthanorequalto 1} L = {a^n b^n a^m: n greaterthanorequalto 0, m greaterthanorequalto 2} L = {a^n b^n a^m: n greaterthanorequalto 0, m greaterthanorequalto 1}
