Following is the code for two threads T1 and T2; x and y are global variables initialized to 0.

T1:                   T2:

x++                  while (x==0)     ;    //busy wait

y++                  x++

                        y++

  • What is the value (or possible values) of x and y, after T1 and T2 finish executing?
  • If the final value of y can be something other than 2, fix the program so that the value is always 2. Use busy waiting (no atomic instructions, no semaphores).
