Define a language that is not a regular language using a

Define a language that is not a regular language using a context-free grammar that is not ambiguous. The alphabet of the language must contain at least five characters. Describe in English the strings of the language. Choose any string that is in the language and demonstrate that it is in the language by showing the leftmost derivation that derives it. Draw the parse tree that corresponds to the leftmost derivation. Give an example of one string that is not in the language
