Design a class template for the ADT Hash Table, using the implementation described in this section. The basic operations should include (at least) constructors, a destructor, a copy constructor, inserting an item into a hash table, searching for an item in the hash table, and deleting an item from the hash table.
Use random hashing for the hash function and chaining to resolve collisions. You should also write a driver program to test your class template as instructed in Programming Problem at the end of this chapter.
Problem ,
Write a program that reads a collection of computer user-ids and passwords and stores them in a hash table. The program should then read two strings representing a user's id and password and then check whether this is a valid user of the computer system by searching the hash table for this id and password.
Write a method to count the number of items in the BST (Note that you should do this by traversing the BST and not in any other way). The method returns an integer.
What is the role or place of structured methodologies, data, and algorithms? What differs between object-oriented and object-based languages
In quicksort, instead of selecting three elements, as is done for median-of-three partitioning, suppose we are willing to select nine elements.
Write a client method that returns a count of the number of nodes in a binary search tree that contain a value less than or equal to the argument value.
Propose an efficient data structure that may hold the tour operator's data using a normalization process. Describe each step of the process that will enable you to have a 2nd Normal Form data structure.
Find a simple algorithm for solving following problem and categorize it using big-theta notation: Divide the group of people into two disjoint subgroups (of arbitrary size) such that difference in total ages.
What are the reasons for object orientation? What is the relationship of the object model to the data structure
You will create a Word document to do following tasks: Describe your scenario company. Explain the benefits and disadvantages of each data structure.
As queries are expensive, you would like to calculate median using as few queries as possible. Provide the algorithm which finds median value using at most O(log n) queries.
Several functions have an almost infinite number of input values. Testing all of these values is not possible in most cases, and does not necessarily tell us more than testing a few prices.
Consider the initial layout for Example, which appears in Figure 11-11. Draw a figure showing the layout obtained from exchanging the locations of A and D.
Discuss why it is important to learn how to implement data structures, even though the STL is available. Identify advantages of knowing data structures in detail.
