Before entering a priority critical section, a thread calls a PriorityLock::enter(priority) method. When the thread exits the priority critical section, it calls PriorityLock::exit(). If several threads are waiting to enter a priority critical section, the one with the numerically highest priority should be the next one allowed in. Describe your general approach in implementing a PriorityLock object.

Define the state and synchronization variables for a PriorityLock object and describe the purpose of each

Implement Priority lock::enter(int priority)

Implement Priority Lock::exit()
