I don’t know how to handle this Computer Science question and need guidance.
To verify that a string of characters belongs to a language defined by a grammar, we must create a parse tree that shows that the string can be generated by the grammar.
Consider the following grammar:
<list> -> <item> , <list> | <item>
<item> -> <left> <item> <right> | <left> <right>
<left> -> A| B | C
<right> -> x | y | z
Choose a string that is in this language and create a parse tree that demonstrates that your claim is true. Identify another string that contains some of these terminals symbols but is not in the language.
