Read given code RaceOrNot$1.$java and write all possible outputs of the program when it is run as $$java RaceOrNot$13.$ If you believe there is only one possible output, you just need to write that output.

Code:

$//$Can you rewrite this program into an equivalent program using Lock or Semaphore instead of using synchronized?

public class RaceOrNot$1$ implements Runnable $\{$

static int num$\_$threads;

static int $[]$sa$=\{0,0\}$;
