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)

1. Consider the scenario where a user, Andy, wants to use their banking application to transfer funds to another user, Sam, in the same bank. To do this, Andy's application sends a message to the bank's server authorizing the transfer of funds. In the following illustration, please draw a logical diagram of the steps Andy's banking application would take to ensure that the bank's server can confirm the integrity of the incoming message and authenticate it. Your diagram should very clearly state the transformation happening to the message at each step, and the final version of the message that is sent to the bank's server. Please use the following notation.
