22. (35 points) Memory Allocation Monitor: suppose there are two operations: request (amount) and release (amount) where amount is a positive integer. When a process calls request, it delays until at least amount free pages of memory are available. Processes return amount pages to the free pool by calling release. Each time amount is generated randomly. The memory has a capacity of C equal to 1024 pages. A process shouldn't require more than allowed_limit (initialized to 64) pages. If amount is greater than allowed_limit, then the process should execute a new request (amount). a) Develop a monitor to synchronize processes. You can use two methods named: request amount) and release (amount) (draw the monitor picture, give the thread execution pseudo-code, give service methods' pseudo-code, initialization, condition variables) Use the concept of monitors: cond var have names, are implemented as queues with FIFO policy.You can use any of the two signal policies but specify which one you use. Don't use! notifyAll
