Please understand that you need to use the EBNF notation to describe the syntax. If you don't know what it is, don't attempt it.

Also please don't copy from other chegg answers, I have read them and they are wrong. If you give me a copied answer I will downvote.

Thank you.

|Use EBNF notation to describe the syntax of the following language constructs. (a) A Java return statement, which could be either a return keyword followed by a semicolon, or a return keyword followed an expression then followed by a semicolon. Assume the grammar for expression has been defined as expr -> (b) A Python return statement, either a return keyword, or return one or more expressions separated by comma. (c) Based on your syntax definition in (b), is return x+y; a valid Python return statement
