Write the required functions and script that prompts the user for the name of a file representing a finite automaton: indicating its states and input->state transitions; reads the information in the file (storing the finite automaton in a dictionary); prints the finite- automaton/dictionary in a special form; prompts the user for the name of a file storing the start-state and inputs to process (each line in the file contains this combination); repeatedly processes these lines, computing the results of the finite automaton on each input, and then prints the results. Note that a finite automaton is really a program; in this problem we are reading a program from a file and then executing it (runn
