1. 35 Points] Give context-free grammars for the following languages: (c) wEfa, b, c}* : |w = 5na(w) +2n(w)}
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...
indicate what language is generated by the context-free grammar. The alphabet is Σ = {a, b} • S → SaS | bS
Automata Theory Give a context-free grammar producing the following language over Σ = {0, 1}: {w : every odd position of w is 1 and w = wR} (HINT: All strings in the language will be of odd length).

Give a context-free grammar for the following language over = {0, 1}: L={w : w is not a palindrome}
Q1: Given the below language and context free gramma:, a. Show that the grammar is ambiguous using the string ( abc) by using substitutions. b. Then design a push down automata that recognizes the language. C. Then show the tracing of (abc, abbccc) using the push down automata. d. Then Show which two simple languages create the greaterlanguage. Give set builder notation for each language. e. Then produce Chomsky normal form for the grammar. The following context-free language is inherently...
