(choose chapter or problem)

Consider a planet where everyone belongs to a family of six, every familylives in its own house, each house has a unique address, and each person in agiven house has a unique name. Suppose this planet has a mail service thatdelivers letters from source house to destination house. The mail servicerequires that (1) the letter be in an envelope, and that (2) the address of thedestination house (and nothing more) be clearly written on the envelope. Supposeeach family has a delegate family member who collects and distributesletters for the other family members. The letters do not necessarily provideany indication of the recipients of the letters. a. Using the solution to above as inspiration, describe a protocolthat the delegates can use to deliver letters from a sending family memberto a receiving family member.b. In your protocol, does the mail service ever have to open the envelope andexamine the letter in order to provide its service?
