Implementing Polynomials using Singly Linked List in C++

1. The Term Class
   
   Create a class to represent a term in an algebraic expression. As defined here, a term consists of an integer coefficient and a nonnegative integer exponent. E.g.
   
   • in the term 4X², the coefficient is 4 and the exponent 2
   • in -6X⁸, the coefficient is -6 and the exponent 8
   
   Your class will have a constructor that creates a Term object with a coefficient and exponent passed as parameters, and accessor methods that return the coefficient and the exponent
   
   
   II. The Polynomial Class
   
   Now create a class to represent a polynomial. As defined here, a polynomial is a sequence of terms. E.g.
   
   1. 3X² + 4X⁴ + X⁶
   2. 2 + 5X² + 6X³ + 2X⁷
   3. 4X¹⁰
   
   The terms of polynomial 1 are (3,2), (4,4) and (1,6). The terms of polynomial 2 are (2,0), (5,2), (6,3) and (2,7). Polynomial 3 has only one term (4,10)
   
   F To receive credit for this assignment, your class must use a generic “List of Term” to store the terms of a Polynomial object
   
   Your class will have a constructor that creates an empty list and additional methods to do each of the following:
   
   1. insert a new term in its proper place in a polynomial (see “Additional Specifications,” below)
   
   2. return all the terms of a polynomial as a single line string, as shown here:
   
   3x^2 + 4x^4 + x^6
   
   3. delete a term from a polynomial (see “Additional Specifications,” below)
   
   4. Compute and return the derivative of all the polynomial

5. reverse the order of the terms in a polynomial (see “Additional Specifications,” below)


III. The Test Class

The main method of your test class will create a Polynomial object and then read and process a series of operations

The operations are:

1. INSERT X Y

Insert a new term with coefficient X and exponent Y into its proper place in the polynomial

(insert method : adds terms to the list in descending order of power)

2. DELETE X Y

Remove the term with coefficient X and exponent Y from the polynomial

3. REVERSE

Reverse the order of the terms of the polynomial

4. 1^st DEV

          to find the first derivatives of the polynomial

   2^nd DEV

         to find the second derivatives of the polynomial

Each operation is to be carried out by calling a method of the Polynomial class

Each operation read must be “echo printed” to the screen

After each operation, print the updated polynomial by calling the toString() method

For the Derivatives operation, print the string returned

IKEA is a leading home furnishing company with around 340 stores in 40 countries, selling a range of some 10’000 articles and having more than 150’000 employees. The company was founded in 1943 by Ingvar Kamprad in Småland, a province in Southern Sweden where people are renowned for working hard, being thrifty and innovative, and achieving big results with small means. Today, the IKEA group is controlled by a private foundation and the company is thus not on the stock market. Ingvar Komprad’s innovative idea was to offer home furnishing products of good function and design at prices much lower than competitors by using simple cost-cutting solutions that did not affect the quality of products. This is a prominent philosophy at IKEA, which is now realizing its ambitious plans in Russia. IKEA opened its first store in Moscow, Khimki, in March 2000, followed by one more in Moscow in 2001, one in St Petersburg in 2003, and one in Kazan in March 2004. In 2012, IKEA had 14 stores in Russia and some of them in distant places such as Novosibirsk (2007) and the newest ones in Ufa (2011) and Samara (2012). All Russian operations are controlled as fully owned ventures by the IKEA group. IKEA is characterized by a strong brand based on its vision to create a better everyday life for many people. A set of explicit values is linked to the vision and plays a guiding principle in the strategy development. The values are the foundation of a culture called internally the ‘IKEA Way’, which is an expression of lKEA's history, the product range, the distribution system, the management style, the human resource idea, etc. Brand and cultural values coincide and affect the strategy, organizational processes product development and customer relationship. Thus the key value of cost-consciousness that lies at the heart of IKEA's flat-package concept dictates the necessity of global sourcing, define the customer relationship where 'IKEA does a half and customers do a half' and guides the product design, choice of material and logistics. The value of simplicity is reflected in the fast planning process, behaviours and routine governed by common sense, straightforward relationships with suppliers and customer as well as in the product development process. By linking vision and values, IKEA thus create a firm platform for entering a new market. In each new market lKEA enters it must recreate its company culture from scratch. In Moscow that included the replication of the store design and layout in accordance with the latest version of the existing store and extensive cultural education that was implemented by the team of experienced IKEA people. It was the overall company vision that guided the desire to establish business in Russia; most particularly, the impression that few companies in Russia focused on solving the needs of the many people by offering attractive products at reasonable prices. However, knowledge of the Russian market when IKEA initially decided to open its first store in Moscow was very scarce. No special market research was carried out before setting up the store. IKEA’s basic strategy is to neither adjust the style of products to local needs nor follow the competitors’ products development was central as the cornerstone in preserving the IKEA concept and image: ‘The range is supposed to be IKEA – unique and typical IKEA’. All products are divided into four major categories or styles – Scandinavian, Country, Modern, and Young Swede – which are clearly distinguished in all business areas across the store. One of the reasons why IKEA was successful with its standard product ranges in Russia was the fact that several of these IKEA ranges emphasis the modern style, which is very different from the traditional Russian style but is attractive and fresh for the Russian customers because it symbolizes change. An important factor in the market approach was to identify needs that are not fully recognized and to teach customers what IKEA is about. IKEA's retail proposition is based to a large extent on its Swedish roots and history, which is, in turn, very different from Russian traditions. Therefore, learning as much as possible about the local culture and customer needs was considered essential. For example, IKEA made home visits to customers to talk to people, see how they lived and used their homes and to identify potential needs and wants not fully acknowledged by customer themselves. Understanding local family conditions and furnishing traditions then provided a basis for the effective introduction and marketing of the IKEA concept. As exemplified by a store manager, the main priority for Russians is normal living costs; then comes the car and TV; and afterwards maybe a trip abroad. The idea of changing people's priorities by explaining to them that a beautiful home does not have to cost a fortune and they can afford both the wardrobe and a trip abroad is an essential leitmotif of the marketing campaigns in Russia. The importance of aligning the IKEA concept with the desired image was critical from the very beginning. The intention was to build an image with a low price brand that also guaranteed attractive and modern products of good quality. To achieve this, IKEA has faced many challenges such as: high customs fees; the requirement to purchase more from the local producers; difficulties in finding and developing suppliers in Russia; still low buying-power of Russian customers etc. For IKEA, it was critical to associate the low price with the desired significance. An increased capacity and bigger volumes by the Russian suppliers will allow the company to cut costs and reduce prices in Russia as well as to export the Russian made furniture to its other markets. As a matter of fact, IKEA prices are still very high for many ordinary Russians. For example, even in St Petersburg, the second-largest city, shopping power is, according to different estimate, 30 to 50 per cent lower than in Moscow, where an average purchase value equals that in Stockholm. But for Russian customers low price was very strongly related to unattractive products of poor quality, and one challenge has been to overcome this and explain how it is possible to offer good product at low prices. Therefore, it has also been an ambition to provide the Russian market with the best and most attractive IKEA products. Marketing communications became an important tool in creating the right image of IKEA in Russia. The ways to communicate the image were many: the outdoor product ads (price), image ads in the glossy magazine, TV (though IKEA has used this very restrictively due to high cost), and articles in the newspapers (press coverage has become very broad and quite positive towards the IKEA culture and philosophy). Another very important communication means in Russia is the buzz network or word-of mouth communication that works very effectively. In addition, IKEA had an open and friendly approach towards Russian journalists. This was in sharp contrast to most other large organizations. IKEA was completely open to the journalists and introduced them to the IKEA way and values by organizing press trips to Älmhult in Sweden to learn how the range is created. The result was that the press coverage of IKEA in Russia became much more positive. In the spring of 2009 IKEA thus had 11 stores operating in Russia. Most of these locations were mega mall shopping complex operated by IKEA. The shopping complex at the Tyoplyi Stan site in Moscow for example accommodate around 210,000 square meters of retail space and 240 retail outlets. The mega malls were treated as a separate business, and were an addition to IKEA's core concept. Normally, IKEA does not manage or develop shopping centres but this was considered necessary in Russia due to its lack of an existing structure of large branded stores and external as well as central shopping centres of a Western kind. Previously, many Russians have shopped for furniture as well as other products in outdoor markets or at smaller, local stores. From IKEA’s perspective developing a whole mega mall was part of attracting Russian customers to the stores. As a whole, IKEA has made substantial investments in Russia, and turnover is increasing rapidly. However, a major principle has been that monetary returns are needed to back up further expansion: ‘As soon as we make a profit, I can see at least ten years ahead when we will need all the money that is generated in Russia. So, the day when we will start to take out profit from Russia and use it in other countries is perhaps 15 years away'.

In C++, please build a simple Distance Vector program that will communicate with N partners and do the following. (NOTE: All connections between a server and clients should be TCP/IP socket.)

1. You will run N instances on your machine
2. Each instance will run on a different port (instance 1 will run on port 18181, instance 2 on port 18182, instance 3 on port 18183, etc)
3. The program will start by reading in the appropriate neighbors file and vector file.
4. The program will ONLY read vectors where the fromNode is equal to that node. For instance, node 1 will only read in vectors where node1 is the fromNode.
5. The program will support the following requests from clients:
   1. Show files at the server’s current directory: ‘print’
      1. This will print the current vector table on a node.
      2. ONLY print valid vectors (don’t print uninitialized ones)
   2. Download files: ‘refresh’
      1. This will force the current node to send its vector table to all its neighbors.
   3. Upload files: ‘update’

1. This will be of the form: Update fromNode toNode cost
2. Update checks that the toNode is the current node. If it is not it is ignored
3. Update then checks if the toNode-fromNode exists in vector table. If it does not it is added and neighbors are notified
4. If the pair is in the table, and if the new cost is less than the old cost, that cost is stored and the neighbors are notified.
