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...

1. Give a context-free grammar for the set BAL of balanced strings of delimiters of three types (), and . For example, (OOis in BAL but [) is not. Give a nondeterministic pushdown automata that recognizes the set of strings in BAL as defined in problem 1 above. Acceptance should be by accept state. 2. Give a context free grammar for the language L where L-(a"b'am I n>-o and there exists k>-o such that m-2*ktn) 3. Give a nondeterministic pushdown...
Give a context-free-grammar describing the syntax of the
following language.
Thank you =)
Give a context-free-grammar describing the syntax of the following language: L = { ww| we{a, b }" } is a context- free language, where w is a non-empty string from alphabet {a, b } and wt denotes the reversal of string w.
Give a Context Free Grammar (CFG) for the following language: L = { w | the number of a’s and the number of b’s in w are equal, ∑= {a, b} }
Find the context free Grammar for the following language L = {w ∈ {a, b, c}* : na (w) + nb (w) ≠ nc (w)}.
