Please find the best methodology for each of the three software development personalities below and explain why you chose that one en each case.

1. The NinjaSix:

“Show don’t tell” describes his modus operandi best. He is an enigma: not outright friendly or forthcoming, but he works surprisingly well on a team.

His motto? Don’t have doubts; just resolve the problem quickly and efficiently. This no-nonsense attitude makes him an absolute joy to work with.

2. The Clever Ambassador:

He is outspoken and the unofficial project manager. He is the consummate ring-master, able to please both clients (the ferocious lions) and team members (the elephants that could easily trample him if they wanted).

works behind the scenes, receiving lower pay for what amounts to the same work

3. The Half-Cup Speedster:

The half-cup speedster takes on multiple projects at once. He works much faster than most, but his amazing quantity is tarnished by its quality: his speed results from cutting corners and hacking core.

Unfortunately, much like the handwriting of physicians, his code is practically indecipherable. Should someone need to fix a problem that surfaces later, they will surely encounter difficulties. You can’t fix what you can’t read or understand.

1. Create a Huffman Tree and generate the codes for each character of the following input:

create a huffman tree

For consistency:

1. If same frequency – put in priority queue alphabetically; put space before other characters of the same frequency

2. Add subtrees to end of group with same priority

3. Lower number has higher priority (goes to front)

The Government of Mauritius, through the Smart City Scheme from the Economic Development Board (EDB), is offering a plethora of opportunities to global investors to share in the vision of Mauritius in creating intelligent, innovative and sustainable cities of tomorrow.
One IT concept critical to the implementation of smart cities is what we refer to as the "Internet of Things", commonly known as IoT.
a) Explain, using a relevant diagram, what is IoT?
b) List and explain two benefits that IoT will bring to smart cities in Mauritius.
c) List and explain two limitations of IoT.
d) Will smart cities be a success in Mauritius and will it achieve its main goals? Discuss

In Java:

Problem 1.

Write a program that performs the following two tasks:

1. Reads an arithmetic expression in an infix form, stores it in a queue (infix queue) and converts it to a postfix form (saved in a postfix queue).

2. Evaluates the postfix expression.

Use the algorithms described in class/ lecture notes. Use linked lists to implement the Queue and Stack ADTs. Using Java built-in classes will result in 0 points. You must use your own Stack and Queue classes (my code is a good starting point). Submit the code + example runs to validate your code. Submit UML chart to show the program design.

Problem 2.

Given the following postorder and inorder traversals of a binary tree, draw the tree:

Postorder: A B C D E F I K J G H

Inorder: C B A E D F H I G K J

Explain your answer in a systematic and recursive fashion.

Ms. Asma Ahmed is the new director of the Al-Ekra University library. Your team has been contacted by Ms. Asma to develop a software system for the library only. She has prepared a description of some basic functions of the library loan system currently done manually. Ms. Asma wants an automatic library system that should work as described below: “The library loan system that we have at present is mostly manual. The library has three types of items for loan to its members: Book, DVD, and Magazine. Each item is identified with a unique call number of six-digit long. The item has also a title and year of publication/production. Not all items are for loan. Some items are only for use inside the library. For a book, 4 weeks; for a DVD, one week; and for a magazine 2 weeks loan is granted if the item is available for loan. A member can borrow maximum of 5 items. The library maintains three different file systems: Membership, Item, and Loan. The university has also a separate software system called Unisys that deals with students and staff. The system has three major components: Staff/Student data, Registration data, and Course data. However, our library system needs data from UniSys to check the validity of the membership of the library. The university has another software system that deals with finance and payments, called FinSys which is also independent but communicates with other systems in the university. It has three components: Financial account of the staff/student, Salary, and Expenditure. Every person at Al-Ekra University has a FinSys account called Fin_Account. The information on the salary of the staff and the tuition fee of the student are stored here. We now want a library system that can provide the following functions. The member of the library can only borrow items from the library. The person must be either staff or student of Al-Ekra University. The person first submits an online application form. The forms include the name and address of the person, and the Fin_Account of the person with Al-Ekra University. A library administrative staff is immediately informed by the system that an application has been submitted. The admin staff first checks the application, and provides input if needed. The system saves the updated information of the application, and then contacts UniSys to get the confirmation that the applicant is either staff or student. Once the library system gets the feedback from UniSys, it records the feedback. If the person is a member of the university, the application is preliminary accepted; otherwise the application is rejected without further processing. The library system then requests FinSys to transfer QR. 500 from the applicant’s Fin_Account to the library. Once the money is transferred, the system creates a library membership account, and deposits the money in this account. After transferring the money to the library system, FinSys records in the applicant’s Fin_Account that QR. 500 has been transferred to library. Finally, it produces a membership card, and assigns a unique membership number. The system finally sends the membership card to the member. If FinSys does not transfer money, the system generates an error message to enter valid Fin_Account. Every team member MUST read this document carefully Page 2 In order to borrow an item from the library, a member first enters the membership card into a card reader of the library. The system retrieves the membership details and contacts the university system UniSys to find if the member is an active staff or student. If not, the system does not allow the member to borrow any item from the library and terminates the function. Otherwise, the system asks the member to place the item in the scanner. Once the member does this, the system gets the item details and its type. It also checks if the item is available for loan. The system also finds out the total items already borrowed but not returned. If the item is available for loan, and the total item borrowed but not returned is less than 5, it makes a loan for the member. The item is included in the membership account with the borrowing date and due date for return. The system then increments the total borrowed items by 1, and it makes the item unavailable for other members. The system also decrements the total items reserved of the member if the item was reserved by the member. The member has also choice to request for extended loan time for one more week. If the item was not reserved, one more week is added with the original return date. Finally, it creates a receipt of the loan, and releases the security code of the item. The receipt includes information such as membership number, item call number, loan date, and return date. A member can return a borrowed item to the library by scanning the item into the system that finds the loan details. It then checks the due date. If the due date already passed, it calculates the fine based on number late days. The system updates the member account with the fine. It then makes the item available and sets the security code of the item. The system decrements the total item borrowed by 1. It then creates a receipt of the return. The members can also extend the return date of an item if not reserved by other members. The member first inserts the membership card into the card reader. The system retrieves the list of all currently borrowed items. The member then selects the item that he/she wants to be extended. The system finds the current return date. If the return date has already passed, no extension is possible. An extension is only possible if the request is made before the return date. It also checks if the item has already been reserved. If reserved by other, the return date cannot be extended, otherwise one week extension is made. The system updates the member account with the new return date. It prepares a receipt with the new return date. A member can reserve an item if it is currently on loan with other member. The member first enters the card into the card reader. The system finds the membership details. It checks the total number of current reserved items. It the member has already reserved 3 items, no more reservation request is possible. The system asks for the call number of the item he/she wants to reserve. The system retrieves the item details once the member enters the call number of the item. If already reserved by other, it cannot be reserved by anyone. If not, the item is reserved under the member account, and increments the total reserved item by 1. The system confirms the reservation to the member. Every day at 10 am, the library system automatically checks if any item was not returned after 10 days of the due date. The system generates a list of such items and alerts the admin staff with the list. The staff then enters the call number of each item into the system which finds the loan details. It changes the status of the item as ‘lost’. The system deducts QR. 500 from the deposit money as a fine from the member account. It then requests FinSys with the Fin_Account of the applicant to transfer QR. 500 to the library. FinSys forwards the transfer information to the library that receives the advice and updates the member account with the deposit money. The member is informed about the lost item. The system should know which item was borrowed by which member, borrowing date, the return date, if the item was returned and when. It can also find out which item was lost and by which member, how many items were borrowed by one member, which item was borrowed by which members so far, etc. " Page 3 Ms. Asma wants that the managing of the above activities of the library should be automated as much as possible. There will be also possibility that the administrative staff can generate summary report of loans, returns, fines, etc. At this stage, she wants you to analysis ONLY the functionalities of the library system. She also warns you that you should not analyze any functionality of other systems in this phase. You need to define the system boundary carefully.

In python I have my code written and I want just 4 functions to be fix in my code according to rule. My code is running but it has some problem regarding to rules. (I have did all the other things so you do not have to worry about other functions)

1) all the players has to play until he/she reaches to at least 500 points in first round.

When user reach 500 points for the first time, user may choose to immediately end his turn to prevent losing the points.

If you user did choose to save his turn and if he get farkle the score will be 0. (This is just for the first round.)

2) fix my scoring according to point table.

point table for game:

5 = 50 points

1 = 100 points

Triplet of 1 = 300 points "Example(1,1,1)"

Triplet of 2 = 200 points

Triplet of 3 = 300 points

Triplet of 4 = 400 points

Triplet of 5 = 500 points

Triplet of 6 = 600 points

Four of a Kind [Example(4,4,4,4)] = 1,000 points

Five of a Kind[Example(4,4,4,4,4)] = 2,000 points

Six of a Kind [Example(4,4,4,4,4,4)] = 3,000 points

(1,2,3,4,5,6 ) = 1,500 points

Three Pairs [Example(4,4,2,2,1,1)]= 1,500 points

Four of a Kind + a Pair [Example(4,4,4,4,1,1)]= 1,500 points

Two sets of Three of a Kind [Example(4,4,4,6,6,6)] = 2,500 points

NOTE(single 2,3,4,6 does not have any point.)

3) there are six die in game and I have already implement it but it not working as rules.

computer have to Take out any dice worth points after each roll.

user has to Roll the remaining dice,

removing any dice worth points and adding them to your running total.

If user are ever able to set aside all six dice, user can roll again all of his dice and keep building his running total.

If ever user are unable to set aside any dice ( dice contain 0 points), user have Farkled. user lose his running point total and his turn is over.

4) Winning (I have also did little bit but i want to make it simple so can you see it and fix)

If any player score 10,000 points in game

The end game sequence will start

Each other player has one turn to try to beat score of player who scored 10,000 points.

After all remaining players have had their turn, the player with the highest score wins.

you should enter the number of players as a parameter ( 2 to 6 players) .
