BizMic Multiples BizMic Multiples is an IT company that manages the Gauteng Province database system. In the past, they built a system that stores and accesses records of all the SA citizens in Gauteng Province in a direct access table. A direct access table involves the creation of a big array and uses phone numbers as an index in the array. As time goes on and the population continues to grow, it has now become very difficult to access a record from the traditional method. The system has now become very slow due to a large amount of records stored in it. The BizMic Multiples IT Company has consulted with an auditing firm who recommended a system that uses an array that stores pointers to records corresponding to a given record. This system, known as Hash Data Structures or simply Hash Table, is intended to improve on the existing system. As the lead IT intern at BizMic Multiples, your unit (you and your team members) is saddled with the responsibility of overseeing the success of the recommended system. You are expected to implement the insertion and deletion components of the system. Also, the system should accept the inputs from a user. For a test case, assume the list [1, 2, 3, 4, 5, 6, 7, 8, 9, and 10 as input to the system. That is the id of people to be stored in the system.  Using Java NetBeans implement the Hash Table insertion and deletion operations in the scenario above and display the outputs accordingly, showing a step by step process for each operation.
