Memory Allocation. Suppose there are two operations: request(amount) and release(amount), where the amount is a positive integer. When a process calls request, it delays until at least amount free pages of memory are available. a process returns amount pages to the free pool by calling release. Pages may be released in different quantities than they are acquired.

a) Develop a monitor that implements request and release. First specify a global invariant. Do not worry about the order in which requests are serviced. Use the signal and continue discipline.(hint: use a covering condition.) ( Hint: The covering condition refers to the single condition variable newPages on which any process must wait when the number of free pages is less than amount)
