Read a description of a non-deterministic finite-state automaton in the AT&T format (without weights) from the file in the first argument. Read strings from the standard input. If a string is accepted by the automaton, write YES, otherwise- write NO. The program is invoked like this: python run.py test1.arg < test1.in > test1.out Note that not all transitions must be included in description. If no transition is given for the given state and letter, write NO. POINTS: 3 DEADLINE: 2021-11-20 23:59:59
