Question: Suppose you have a context - free language that only includes strings which are palindromes over the alphabet = { x , y } :

Suppose you have a context-free language that only includes strings which are
palindromes over the alphabet ={x,y} :
Describe the corresponding context-free grammar.
Solution.
G=({S},{x,y},R,S) with rules:
SxSx|ySy|x|y|
