Write a program for a deterministic push-down automata simulator. in this case, though, your simulator should include a stack that follows the rules of a push-down automata. keep in mind that you will need to change your input file so that the transitions are of the kind , i want this to be as general as possible, with the machine defined in an external text file. the output of this can be the same as the dfsm simulator. simply indicate whether the machine accepts or rejects each input string. in java .

Use a physical stopwatch to record the length of time it takes to run the program. calculate the difference obtained by calls to the method system.currenttimemillis() just before the start of the algorithm and just after the end of the algorithm. calculate the difference obtained by calls to the method system.currenttimemillis() at the start of the program and at the end of the program so that the elapsed time includes the display of the result. use the value returned by the method system.currenttimemillis() just after the end of the algorithm as the elapsed time.

Two students are discussing the flow of electricity. student a says that voltage is a measure of the amount of electron flow in a circuit. student b says that power is the product of voltage and current. which of the following statements is correct? a. only student a is correct b. only student b is correct c. both of the two students are correct d. neither of the two students is correct
