Question
Chapter 2, Problem 1CTQ
Program Plan Intro
Web Browser:
- Web Browser (simply called Browser) is a software program used to explore the content of world wide web.
- The content may be a picture, video, audio, and web pages connected using hypertext links and so on.
- This program is a client side program.
- It uses several protocols like, hypertext transfer protocol (HTTP), for translating the webpage content to human readable form.
- Examples are, Firefox, Opera, Chrome, Safari and many more.
Explanation of Solution
Experience of a person when using various web browsers:
Firefox:
- When the user searches a term in Firefox, it came so fast in loading webpages and it is user friendly.
- User can feel that it is getting stuck with some websites especially with Facebook.
- While using more tabs in Firefox the user feels its bit slow.
Opera:
- While using Opera, user can feel the speed of browser in loading web pages.
- It lets the user to pin the icons to toolbars and its home page so that user can get to the same website easily.
- Some of the users say that it is not a secure browser available now...
Explanation of Solution
Best web browser:
- When compared to other browsers Firefox is the best. Firefox has an edge for ease of use.
- It provides faster performance compared to other browsers.
- It has an interface that is well designed...

Suppose that the two Rank methods below are added to the Skip List class on Blackboard.
public int Rank(T item)
Returns the rank of the given item.
public T Rank(int i)
Returns the item with the given rank i.
Requirements
1. Describe in a separate Design Document what additional data is needed and how that data is used to
support an expected time complexity of O(log n) for each of the Rank methods. Show as well that the
methods Insert and Remove can efficiently maintain this data as items are inserted and removed. (7
marks)
2. Re-implement the methods Insert and Remove of the Skip List class to maintain the augmented data in
expected O(log n) time. Using the Contains method, ensure that added items are distinct. (6 marks)
3. Implement the two Rank methods. (8 marks)
4. Test your new methods thoroughly. Include your test cases and results in a Test Document. (4 marks)
