You have a hash table of length 7 (tablesize 7). You are given a hash function f(x)-x % tablesize, where x is the value to be hashed and fix) is the hash address. Quadratic probing is used to resolve the collisions. The hash function receives the input 40, 26, 15, 12, 5, 17) in that order. Place each number in hash table in its correct address. The first two values are already placed in their correct positions If there isn't...

Design a primary hash table data structure. a. Each hash table has an array of node pointers and can point a head of a linked list. Suppose the node class is given to you. The data type of each node is int. b. Override the default constructor with a constructor that has one default parameter called capacity. What happens to your default constructor? Create some instances of the sequence class using the new constructor in multiple ways. c. Design the...

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...

Linear Hash Table
2. In this first question you will apply the specified operations to instances of LinearHashTable (i.e., hash tables that use the "linear probing" approach as it was discussed in class). When such a hash table is first created, it has dimension 1 and an initial length of 2, and subsequent operations might require that the underlying array be resized, so for each of the questions below, start with the hash table specified and demonstrate (by drawing the...
