Q1. Sum Matrix Game [20%]
Sum Matrix is a number placement game.
In this game, an n x n matrix is filled with numbers such that (1) the sum of the numbers in each row or
each column is all same, and (2) all the numbers from 1 to n*n should be placed in the matrix. The
program should develop the matrix based on the following given rules.

1. The program should ensure the input value n as an odd number in the range of 1 to 11. Otherwise,
   the program should display the following message and terminate: Please enter an odd
   positive number in the range of [1-11]. Bye.
2. The possible range of values in each cell of the matrix should be a product of the input odd number.
   • E.g., For sum matrix of order 3*3, the cell values should be in the range of (1-9)
   • E.g., For sum matrix of order 5*5, the cell values should be in the range of (1-25)
3. In the output, set the width of each column of the matrix to 4 characters and there is one space
   to separate two columns.

4. Note that the cells in your matrix may have different values. (There are multiple solutions, and
   you only need to generate one possible solution.)
   Hints:
   • Observe where to place“1”in a particular matrix and the pattern to place“2”,“3”,“4”, and so
   on. You will observe a general pattern.

   Q2. Document Correction and Alignment Problem [20%]
   Nowadays, the natural language processing technology is increasingly more mature. Recently the
   Beetles Phone Technology company released their latest smart phone, Beetles Resolver 66. The most
   eye-catching part of their release conference is not their new smart phone, but rather, a speech
   recognition input method  Taxman input method.
   Now suppose we have a document, and the content of which is generated by a speech recognition input
   method. Due to the error of the speech recognition input method, some continuously duplicated words
   appear in the content. Also, the format of the content is messy because of different length of each line
   (see the content of D1.txt in example).
   You are required to write a program to remove the word duplication and align the content based on the
   following instructions:
   1) Your program can assume that every word in the input document consist of at most 20 characters,
   the input document may be jammed with empty line, but the whole input document represents one
   single paragraph with at most 1000 words. Similarly, your output document should contain one
   paragraph with at most 1000 words.
   2) The given document is a text file, named as document.txt, and the output text file is called output.txt.
   Your program should place it in the project directory of your VS C++ project.
   3) Your program only needs to handle the duplication for a single word, like “The the the world”. The
   duplication for multiple words, like “The world the world”, will not appear in the given document
   read by your program. That is, if there is a consecutive sequence of same word (irrespective to the
   use of capital letters and lowercase letters), then it is a duplication of that single word.
   4) Your program can assume that the following characters consider as punctuations in an English
   sentence: comma and full stop. All other characters are treated as a part of a word. In Example 2 on
   next page,“(Friday)”is a word. In this case,“(Friday) Friday”has no word duplication and
   your program needs not to correct this sequence of characters.
   5) The number of the duplication is indefinite.
   6) Each duplication of a single word should be replaced by a single occurrence of that word after your
   correction. For example, “The the the world” should become “The world” after your correction.
   7) After the alignment, each line should contain exactly 60 characters (contain the space and
   punctuations), with the exception of the last line.
   8) Your program can align the content by adjusting the number of words per line and the space
   between the words. The space number between the words should be determined by the total space
   available and the total words number in this line. There is no space between words and
   punctuations.
   a) E.g., if a line can contain 4 words and 3 spaces, then the amounts of space characters in
   between two consecutive words on this line should be 1, 1, and 1.
   b) E.g., if one line can contain 4 words and 5 spaces, then the amounts of space characters in
   between two consecutive words should be 2, 2, 1.
   9) After the alignment, each line should start with the word and end with the word or punctuations.
   10) No word can be spited during the alignment process.
   11) The result is required to be stored in a text file named as output.txt.

   Hints:

5. Your program may consider using a two-dimensional array to keep 1000 text strings, each
   with a length sufficient to keep your required characters (including the end-of-string character
   ‘\0’)).
6. Your program may consider the logics outlined below.
   a. It read the lines from the given text file line by line.
   b. For each line, identify each word together with a possible ending punctuation
   appending to it and keep that string into an entry in the above-mentioned twodimensional
   array.
   c. Now you keep the whole text document as a sequence of words in an array.
   d. Your program should then compare whether two consecutive words in the array refer
   to the same word. If you find a duplicated word, then you can use your strategy to
   either remove that duplicated work from the array or mark the corresponding entry
   in the array as“duplicated”.
   e. Now, you can scan the array from the first entry and decide the length of each entry.
   While your scanning, you can determine which words to be placed in the same line in
   the output text file together with the number of space characters you needed to
   separate the words in that output line.
   f. You should then output that line to the text file.
   g. Of course, before your program ends, it should close all files opened by it.
7. Your program may use strlen() and strcmp(), strcpy(). Note that in Visual Studio 2019, the
   functions strcmp() and strcpy() are not allowed by default. See Slide 28 of the Lecture note
   L08a to observe how to bypass the limitations. You may use strcmp_s() instead of strcmp()
   and strcpy_s() instead of strcpy(), which are directly supported by VS 2019 by default.
8. Since duplicated occurrences of the same words (e.g., The the the) may be in different
   combinations of uppercase and lowercase characters. Your program may firstly convert them
   into all lowercases and then do a comparison. You may just assume that the first occurrence
   is the one you wish to put into the text file output.txt.

9. A word in the given document may be appended with a full stop or a comma. Since it is a text
   file, a line also ends with the end-of-line character (‘\0’). To identify a word, your program
   should consider whether a word is ended with a full stop, a comma, or the end-of-line
   character.

   Q3. Pointer and Dynamic Array [20%]
   The code on the next page is an executable solution for Exercise 5 of Tutorial 7 on Array.
   Your task is to (1) rewrite the program to perform the same computation that meets the following
   requirements. Note that you can use your own array-version programs as long as your program meets
   the following requirements.
   • Every array in the program is a dynamic array.
   • Exceptthe statement in which it uses of the“new”operator (e.g., int* faces = new int[12];),
   there is no any use of any array construct in the program. (hint: Use Pointers!)
   o For example, all of the following array constructs in the code to refer to the elements in
   the corresponding dynamic arrays are forbidden to be used.
    sum[i + j – 1]
    sum[k]
    sum[index]
    sortedindex
    sortedindex
    sortedk
    sortedk – 1
    sortedk
    sortedk – 1
    sortedi
    sortedi-1
    facessorted[0 – 1]
    facessorted[i – 1]
    faces[k]
   • Every dynamic array must be deleted before the program terminates.
   o Hint: when deleting the 1D array faces, use delete: delete[] faces;
   o Hint: when deleting a 2D array, you need to delete all the rows of the 2D array first, and
   then the 2D array.

    Q4. Recursion
    In tutorial T04, Exercise 4 asks students to develop a program using four nested loops. The tutorial
    exercise is reproduced below.
    Write a program without using any loop (i.e., without any while-loop, for-loop, or do-while loop) to solve
    the same program. I.e., the program should accept a positive integer number N and outputs a sequence
    of lines in the format of p = a^3 + b^3 = c^3 + d^3 where p, a, b, c, d are all distinct positive integers such
    that p <= N and p = a3 + b3 = c3 + d3 and no two lines contains the same set of {a, b, c, d} (in the sense of
    values).
    Your program only needs to handle 0 ≤ N ≤ 1000000.
    Your program should be efficient. For instance, when a user inputs a large number, your program should
    output the correct list and terminates within a reasonable time (e.g., 1 minute). FYI, a correct program
    can produce the output within a few seconds.
    Important Hints:
    • The solution of this question does not require to use any arrays.
    • Students are advised to work on Exercise 4 in Tutorial 4, particularly following the slides 22-27
    to resolve the subproblems stated on the slides. Or else your program will easily incur bugs.
    • Your program will be at least four recursions, one on each of the four variables“a”,“b”,“c”, and
    “d”to enumerate their combinations. The recursion on“d”is nested in the recursion on“c”,
    which in turn is nested in the recursion on“b”, and which is also in turn nested on“a”.
    • Students are advised to study the patterns in the reference solution of Exercise 4 in Tutorial 4. In
    that reference solution, when looping on variable“b”, it needs the information of the current
    value of the variable“a”within the loop body of this loop. Similarly, when looping on variable
    “c”, it needs the information of the current value of variable“a”, and when looping on variable
    “d”, it needs the information of the current values of variables“a”,“b”, and“c”.
    Exercise 4: 1729 is Interesting
     There was an Indian mathematician who was famous for his intuition for
    numbers. When the English mathematician G. H. Hardy came to visit him in
    the hospital one day, Hardy mentioned that the number of his taxi was 1729,
    a rather dull number. To which the Indian mathematician replied, “No! It is a
    very interesting number. 1729 is the smallest positive integer expressible
    as the sum of two cubes in two different ways” .
     Verify this claim by writing a program twoCubric.cpp that
    takes an integer N and prints out all positive integers less than
    or equal to N that can be expressed as the sum of two cubes in
    two different ways: i.e., find distinct positive integers a, b, c,
    and d such that N = a3 + b3 = c3 + d3.
     hint: Use four nested for loops, one for each of a, b, c, d.
     Let’s assume that N is not a very large number.

    Q5. Ash and Pikachu [20% + 10% Bonus]
    In the Pokemon series of manga, Ash is the main character who joins force with Pikachu, a Pokémon, for
    various adventure. We now have the Pokemon Go. In this question, we are going to implement some
    of the concepts involved through C++ classes.
    In this question, your program should allow a user to input: (1) a Pokemon world, (2) a list of Pokemons
    and (3) [For Bonus] the information about a trainer called Ash.
    Ensure that the output follows the format presented in Examples given at the end of this question.
    Important note: Your program can assume the following: (1) the number of Pokemons is at least 1 and at
    most 1000, (2) the name of any object is a cstring consisting of at most 10 characters (including‘\0’), and
    (3) all user inputs are valid.
    • The concept of PokemonWorld is implemented as a C++ class.
    o Each PokemonWorld object owns two PokemonStation objects. We simply refer to each
    PokemonStation object of this class as a station.
    o Each PokemonWorld object is responsible to initialize the two (2) stations.
     (Note: The use of an array to keep two stations will make your program significantly more
    complex than keeping them as two separate variables. The reason is due to our limited
    known-how introduced in CS2311 to use object pointers rather than the limitation of C++.)
    o When a Pokemon enters a PokemonWorld, the PokemonWorld is responsible to assign this
    Pokemon to one of the two stations on its own. The assignment of each Pokemon will be done to
    the PokemonStation in a round-robin manner (i.e., the first Pokemon is assigned to
    PokmonStation1, the second Pokemon is assigned to PokmonStation2, the third Pokemon is
    assigned to PokmonStation1 again, the fourth Pokemon is assigned to PokmonStation2 and so on).
    o The‘name’variable of the PokemonWorld object can be accessed by the object itself.
    o Hint: study http://stackoverflow.com/ques…
    • The concept of PokemonStation is also implemented as a C++ class.
    o Each object of this class represents a station which has a station identifier. We simply refer to
    each object of this class as a station. The station identifiers are s1 and s2, respectively.
    o The identifier of each station is provided by the PokemonWorld object that owns the station
    through the class constructor of PokemonStation. (Hint: You may wish to initialize each
    PokemonStation when the constructor of PokemonWorld object is being called.)
    o Each station maintains its own list of Pokemons assigned by the PokemonWorld object.
    o Both the identifier of a PokemonStation and the list of Pokemons (i.e., each Pokemon that
    belongs to a particular PokemonStation) should not be accessible by any other object nor be
    returned via a function.
    o Only PokemonWorld and the PokemonStation itself can invoke the functions of that station.
    • The concept of Pokemon is also implemented as a C++ class.

    o Each Pokemon is an object of this class.
    o Each Pokemon object has its own name (a cstring) and hp value (an integer).
    o All data members (name, hp) of each Pokemon object once initialized can only be accessed by
    that Pokemon object.
    • The main() function is responsible for the following:
    o To accept all the inputs from the user.
    o To create a PokemonWorld and all the Pokemons.
    o To set each Pokemon to enter the PokemonWorld.
    o To call the method print() of Pokemon, which in turn calls the method print() of each
    PokemonStation, which in turn calls the method print() of each Pokemon to print out the
    information of the PokemonWorld, the PokemonStation, and the Pokemon, respectively.
    Bonus Part [Extra 10%]
    • The requirements stated above should remain intact.
    • A Trainer needs to be implemented as a C++ class.
    o Each trainer (e.g. Ash) is an object of this class.
    o Each trainer has his/her own name (cstring), identifier (integer), and strength (integer). All this
    information is taken from the user as input from console.
    o All data members of each trainer object cannot be accessed outside the trainer object. That is,
    the value of each data member should not be returned via a function nor be retrieved via callby-reference.
    • The main() function is responsible to create a trainer called Ash and let Ash enter the PokemonWorld.
    • PokemonWorld is responsible to guide Ash to visit its two stations one by one once Ash enters this
    world.
    • Each station is responsible to determine whether a trainer can capture each Pokemon kept by the
    station. Specifically, if the hp of the Pokemon is strictly less than (<) the strength of the trainer, then
    the Pokemon is marked as captured by the trainer.
    o Note that following the above requirements, both the hp of the Pokemon and the strength of
    the trainer should not be returned via any function.
    • The print() method of each captured Pokemon calls the print() method of the trainer object that
    captures it to print the information of Ash.
