Question

I need help doing this assignment. This is a java code btw

Problem Description
Implement hash table using linear probing and separate chaining. Java files provided to
you include
HashTable.java: interface
HashTableLP.java: partially completed implementation for linear probing – to be
completed
HashLPDriver.java: driver program to test linear probing – to be completed
HashTableSC.java: partially completed implementation for separate chaining – to be
completed
HashSCDriver.java: driver program to test separate chaining - to be completed
ChainNode.java: chain node used for both approaches
HashException.java: thrown when table is full
Implementation
The hash index is computed as described in the textbook using the Horner's rule.
Lab 5 provides the code for Horner's rule.
An array of ChainNode is used for both implementations. For linear probing, a "linked
list" is either empty or has one node.
HashTableLP.java also needs to report the number of probes needed for each insert,
delete, and retrieve operation performed.
Driver Program
The driver is provided to you. Modify it for different test cases.
Testing
Test cases
table size = 5, number of (key, value) pairs = 3
table size = 7, number of (key, value) pairs = 10
table size = 23, number of (key, value) pairs = 50
table size = 53, number of (key, value) pairs = 50
You may test various table sizes and number of (key, value) pairs. (Reminder: You should
use a prime as the table size.)
