Consider the following statechart diagram, which sketch the behavior of a portable music player (such as iPods) (1) Write a sequence of events that from the initial state will play a song (2) Write the shortest sequence of events needed to get back to the playing state if the battery runs out (3) Is it true or false that the iPod remembers what song was playing when it is docked? Motivate your answer. (4) Is it true or false that sometimes you need to press play more than once to get it to play? Motivate your answer. (4) Modify the above state chart diagram to include the initial situation of a music player, i.e., when you buy it, it has no song on it.
