proces P0:                             proces P1:
while (true)                           while (true)
{                                      {
  flag[0] = true;                          flag[1] = true;
  while (flag[1])                          while (flag[0])
  {                                        {
     flag[0] = false;                        flag[1] = false;
     flag[0] = true;                         flag[1] = true;
  }                                        }
 crit0();                                  crit1();
 flag[0] = false;                          flag[1] = false;
 rem0();                                   rem1();
}                                       }

Can someone give me a scenario with context switches to prove if the above stated code meets the requirements of progress and bounded waiting.

And can anyone give me some tips about how to detect if a code meets the requirements of progress or bounded waiting(and maybe including starvation,deadlock and after-you after you)
