Question: 6. Initial value of shared variable m is equal to 0 and it is stored at memory address 1100 . Four threads A,B,Y,Z use this

6. Initial value of shared variable m is equal to 0 and it is stored at memory address 1100 . Four threads A,B,Y,Z use this variable as follows: Processes A and B increase the value of m by 1 . Processes Y and Z decrease the value of m by 1 . Since m is shared, each process protects the critical region using semaphore S initialized to 2 . Write the sequence of operations so that after each thread is executed once, the value of m is equal to-2. (15 points) ossume the code is used
