Problem 5 (Synchronization, Chapter 2) Write the MIPS assembly code to implement the following C code: lock (flag); larger = max(larger, array); unlock (flag); Assume that the address of the flag variable is in $so, the address of larger is in $s1, and the value of the variable array is in $s2. max () gives the larger value of the two variables. But, you need to use instructions to implement max() instead of using a function call to max () in the critical section as shown, i.e. do not use function calls in the critical section. Usually, we lock the flag by setting it to 1, and unlock the flag by setting it to 0. Please use 11/sc instructions to implement the lock (flag) operation. The unlock (flag) operation is simply an ordinary store instruction to flag
