3. Given the following BNF grammar: -> d c | cd -> a la -> b | b Use the top-down recursive descent method which we discussed in the class to implement a parser (i.e. tdrd.parser.py) in python3 for the above BNF grammar. The input data file name is given from the command line. You may assume that there is a space character between two terminals (e.g. a a adc b ) in the data file.

With respect to the Java grammar, answer the following questions: 1.Determine the shortest possible <synchronized statement>. You do not need to provide a derivation. Just provide the final string. 2.Can import statements appear at arbitrary points in a Java file? Justify your answer using the grammar.
Consider the following data from Selayarese (Malayo-Polynesian spoken in Indonesia). a. Write the phrase structure rules required to form these three sentences. There are two different types of NPs and three different types of VPs (remember subcategorization?). b. Then draw a Phrase Structure Tree for all three of the Selayarese sentences. You will end up with three different Phrase Structure Trees and utilize the Phrase Structure Rules that you generated in part (a). i) La ?allei doe? injo i-Baso. took money the Baso "Baso took the money." ii) Nra ?bai collapsed house the "The house collapsed." sapon injo. iii) Lataroi doe? injo ri lamari put money the in cupboard the Baso "Baso put the money in the cupboard." injo i-Baso.
In general, there are two types of grammars for programming languages, regular and context-free, what is the difference, what is the scope (where are they applied), and how can the use of these grammars produce a higher level of program reliability. Does this higher level of reliability encourage complexity?
