Give a context-free grammar for the following language: L1 = {ww^R c^n : w ∈ {a, b}*, n >= 0}, i.e each string consists of a string w containing a’s and b’s, followed by the reverse of w, followed by 0 or more c’s.

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} }
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 for the following language over = {0, 1}: L={w : w is not a palindrome}
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...
