1. Identify and revise atleast 3 bugs in grammar for Visual Basic Parameter List declarations 2. Identify and revise atleast 2 bugs in the syntax diagram for visual basic parameter list declarations

A parameter list declaration in the declaration of a function or procedure in Visual Basic has the following form: ( parameter_passing_method> As 4type_id>, sudentifier> As stype_id> . jdentifier> As type_id> ) where a parameter_passing_method> is either ByVa_ or ByRef. For example, this is a Visual Basic parameter list declaration: ( ByVal X As Integer, Byval Y As String, ByRef Z As Integer ) and so is this: ( ByRef Apple As Integer) and this: (1 1) Here is a partially correct EBNF grammar for Visual Basic parameter list declarations. Figure out what is wrong with the grammar, and fix the grammar so it is comect. Assume that sidentifier> and type_id> have already been defined by rules elsewhere. [ parameter_passing_method> sidentifier> As 4type_id> > By Val > > ByRef > 2) Here is a partially correet syntax diagram for Visual Basic parameter list declarations. Figure out what is wrong with the diagram, and fix the syntax diagram so it is correct. Assume that identifier and fype_id have already been defined by graphs elsewhere. Paramefer liss declaration
