Q1.7
Provide a context-free grammar in Chomsky normal form that generates the language accepted
by the machine in question 1.4.
You may provide a context-free grammar for partial marks if you can't provide a context-free
grammar in CNGF
You should provide a short explanation of why your grammar is correct, there is no need to
formally prove that it generates the language.
