There are two restrictions on the type of grammars that can be used with a recursive descent parser.

The first is that the grammar cannot have any left recursive productions. Give an example of a left recursive production and explain why such productions would be a problem.

The second restriction is that the grammar must not require more than one token look ahead.

Give an example of a production that does not have this property. Explain why this restriction is necessary for recursive descent parsing.
