a Create MG an augmented PDA from G
b Consider the augmented transition in the PDA created to mimic
the X aXb rule in the grammar. Show the nonaugmented
sequence of transitions required in a standard PDA that would
mimic this rule.
c Let w aacbbacb. Provide a leftmost derivation of w in the
grammar G and show the computation path of w in MG
