Consider the context-free grammar S → ASA | A A → aA | ab When following the CFG-to-PDA conversion process learned in class, there is only one state in the resulting PDA that has a self-loop. Of all the PDA triples on this self-loop, write the shortest one that contains an "a" or a "b" anywhere in the triple in the box below (if there is more than one shortest, write any of them).
