Consider language

Note ωR is reversal of string ω which is true?
  • a)
    L1 regular and L2 is context free language
  • b)
    L1 and L2 are context free language but not regular
  • c)
    L1 and L2 are context free language
  • d)
    L1, L2 are regular
Correct answer is option 'A,C,D'. Can you explain this answer?
Verified Answer
Consider languageNote ωR is reversal of string ω which is ...
L1 = {anωan|ω∈(a, b)*} is regular 
L2 = {ωxωR|ω, x∈ (a, b)* |W|, |x| > 0} is also regular 
∴ Both L1 and L2 are regular Any language which is regular is context free language as well.
