A park rents rowboats online. Part of the online rental process requires each renter to reserve two oars, the number of lifejackets that the renter will need, and a boat before placing the reservation. Write a single pseudo-code algorithm that enables people to run their own software clients to rent and return boats. Use the two-phase locking protocol and make sure to avoid deadlocks! Explain why your algorithm avoids deadlocks. Assume that the locking command is lock(resource, number) where resource is the item that the customer wishes to lock and number is the amount of items to be locked. Assume the results of a call to the lock command are either SUCCESS or FAIL. Assume that the unlocking command is unlock(resource, number), the command to reserve a boat is reserveBoat(), and the command to ride a boat is rideBoat().Write a pseudo-code algorithm for both the lock(resource, number) and unlock(resource, number)
