Closure of Functional Dependency Set

Write an interactive program to implement the closure operator. It works as below: 1) The program first asks the user for the name of attributes. For simplicity let's constrain the names to single upper case characters, e.g., ABCD. 2) The program then prompts the user to input the set of non-trivial FDs. For each rule it first asks for the LHS, then the RHS. Until the user indicates that there is no more FDs. Your program should check the legality of each rule, e.g., the attribute names should be among the ones defined in Step 1, the FD should be non-trivial(with a single attribute on the RHS, and it should not present on the LHS). 3) Within a loop, the program asks the user to type in the set of attributes as the seed, your program then provides its corresponding closure. The program terminates if the user does not want to compute any other closure any more. Note: LHS = left hand side RHS = right hand side FD = functional dependency The program can be done in either C++ or Java ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement). ## Platform c++ or java
