Java question
1) What is a minimal perfect hash function?
2) What is a load factor?
3) What is the load factor for a hash table created using a minimal perfect hash function?
Homework Answers
1.
In perfect hash function, every key is mapped to a different integer(no collision). But these integers might be more than key values. So to make it minimal, the number of different hash values must be the same as the number of keys.
2.
Load factor = no. of different keys/no. of different hash values
3.
Load factor for minimal perfect hash function is 1, since it is a bijective function.

0. Introduction. This involves designing a perfect hash function for a small set of strings. It demonstrates that if the set of possible keys is small, then a perfect hash function need not be hard to design, or hard to understand. 1. Theory. A hash table is an array that associates keys with values. A hash function takes a key as its argument, and returns an index in the array. The object that appears at the index is the key’s...

create a hash table to implement spell checker in java 1. Create a file of 100 words of varying length (max 8 characters). 2. All the words are in lower case. 3. design a hash table. 4. enter each word in the hash table. Once the hash table is created, run it as a spell checker.enter a word (interactive), find the word in the hash table. If not found enter an error message. Then prompt for next word. End the...

in java, Hash 8 randomly generated int values (in the range [ 0 - 99 ] inclusive). The random number generator is initially seeded to value 97. Each generated value is stored in a hash table size 11. The first hash function, h1(key) is the division modulo sizeof(table). I.e., h1(key) = key % sizeof(table) h1(key) = key % 11. Any collisions will NOT be stored in the hash table. You will ignore collisions. The hash table is a random access...

Write a Java program that is able to apply a hash function to a first and last name (key) of a person, and lookup the appropriate index in a hash table modeling a telephone directory. The telephone number (value) should be returned on doing a lookup (you can pre-populate the table with 20 entries for this purpose). You can use existing Java code (or libraries) to model the hash table, however, your program should be customized to use the hash...

IN JAVA LANGUAGE:
For this lab you are required for implement the following
methods:
1. public QuadraticProbingHashTable( int size ):
As the signature of this method suggests, this is a constructor
for this class. This constructor will initialize status of an
object from this class based on the input parameter (i.e., size).
So, this function will create the array HashTable with the
specified size and initialize all of its elements to be null.
