i If A is the starting symbol, then the string zxxyyxz can be derived from this contextfree
grammar. Give three other strings which can also be derived.
ii Explain what is meant by the term "leftrecursive context free grammar" and explain
whether the CFG given above is left recursive.
iii. Draw a parse tree for the following string which can be derived by the above CFG:
zxyyyxz
b Consider the following NFA over alphabet :
i Identify the start and final states of the NFA.
