Add a constructor to SeparateChainingHashST that gives the client the abilityto specify the average number of probes to be tolerated for searches. Use array resizingto keep the average list size less than the specified value, and use the technique describedon page 478 to ensure that the modulus for hash() is prime
Create a newconcrete class that implements MyMap using open addressing with quadratic probing.For simplicity, use f(key) = key % size as the hash function, where sizeis the hash-table size. Initially, the hash-table size is 6. The table size is doubledwhenever the load factor exceeds the threshold (0.5).
Implement a hash table for a given set of keys using the chaining method ofhandling overflows. Maintain the chains in the ascending order of the keys. Design amenu-driven front-end interface, to perform the insert, delete and search operationson the hash table
How many references must you change to insert/delete a node in a single/double linked list? What are the time complexities of finding 10000th element from beginning of a linked list of size n? Understand the method such as AppentToHead, AppendToTail, Delete,...etc and be able to answer questions based on certain scenario?
Create a graphical system that will allow a user to add and removeemployees where each employee has an employee id (a six-digitnumber), an employee name, and years of service. Use the hashcodemethod of the Integer class as your hashing function, and use oneof the Java Collections API implementations of hashing.
All the values are stored in the same place, which is a major drawback of the hashmap we're using (that is, they are all in the same LinkedList). The hash map's intended purpose has been met.
Create a newconcrete class that implements MyMap using open addressing with double hashing.For simplicity, use f(key) = key % size as the hash function, where sizeis the hash-table size. Initially, the hash-table size is 6. The table size is doubledwhenever the load factor exceeds the threshold (0.5).
Develop a symbol-table implementation that maintains twohash tables and two hash functions. Any given key is in one of the tables, but not both.When inserting a new key, hash to one of the tables; if the table position is occupied,replace that key with the new key and hash the old key into the other table (again kicking out a key that might reside there). If this process cycles, restart. Keep the tables lessthan half full. This method uses a constant number of equality tests in the worst casefor search (trivial) and amortized constant time for insert.
Calculate the performance of addFirst, remove(Object), and removeLast for each of the three implementations (Vectors may be included if desired). Which implementations do the best with short lists? Which implementations are the most efficient for huge lists?
Write a hash table in which both the keys and the values are of type String. (NOT generic programming OR a generic class.) Write an implementation of hash tables from scratch. Define the following methods: get(key), put(key,value), remove(key), containsKey(key), and size(). Remember that every object, obj, has a method obj.hashCode() that can be used for computing a hash code for the object, so at least you don't have to define your own hash function. **//Do not use any of Java's built-in generic types; create your own linked lists using nodes as covered in section 9.2.2 of Eck, D. J. (2019). Introduction to programming using Java, version 8.1. Hobart and William Smith Colleges. http://math.hws.edu/javanotes However, you do not have to worry about increasing the size of the table when it becomes too full.You should also write a short program to test your solution.
