Question 1:

CDefs = CDef ["." CDefs].
CDef = CN  Ps.
Ps = P ["," Ps].
P = CN.
CN = Ident.
Main = <s> String.

Consider the above class dictionary A.
Rewrite the class dictionary A without using optional parts
and call the new class dictionary B. Make it as simple as possible.
No optional parts, syntactically introduced with [ ],
are allowed in B. Class dictionary B must define the same language
as class dictionary A.

Put class dictionary B into UNKNOWN1.

Write a method that prints for a given CDefs-object the 
total number of CN-objects the CDefs-object contains.
Your program must work without change for both class dictionaries A and B.
Fill in the UNKNOWN2 below:

void countCN(ClassGraph cg) {
  UNKNOWN2
}
