Question: Say that an NFA is ambiguous if it accepts some string along two different computation branches. Let AMBIG NFA = {N| N is an ambiguous

Say that an NFA is ambiguous if it accepts some string along two different computation branches. Let AMBIG_NFA = {〈N〉| N is an ambiguous NFA}. Show that AMBIGNFA is decidable. One elegant way to solve this problem is to construct a suitable DFA and then run E_DFA on it.
