Possible Section C Questions[edit]

Section C:

State the name of a user defined subroutine - CreateTileDictionary

State the name of an identifier for an array variable - Tiles, Contents, TStringArray, TIntegerArray

Give an example of instantiation - TileDictionary As New Dictionary(Of Char, Integer)

Give an example of a subroutine that returns - (1) - An integer - TTileDictionary (2) - A boolean value - QueueOfTiles.IsEmpty (3) - A string - QueueOfTiles.Remove, GetStarttingHand

Give the name of a built in function - print(), open()

Give an example of an assignment statement - MaxHandSize = 20

Give a name of a subclass that uses iteration and give an example - AddEndOfTurnTiles (For Count := 1 to NoOfEndOfTurnTiles) DO CheckWordIsValid(While...Do)

Give the name of a subclass that uses selection - GetScoreForWord(If Length(word)>7 then Score := Score+20 etc..)

Give the name of a subclass that uses exception handling - LoadALlowedWords (Try...Finally) Why has Try...Finally been used -

State the steps you would have to take in order to add 63.4 players to the game

Name the subroutine that uses a linear search algorithm - CheckWordIsValid (Follow up) Give the time complexity of a linear search- O(n), Disadvantage of Linear search - Has to look through each word step by step to find if the word is valid therefore inefficient

Recursion - N/A

Draw a class diagram for QueueOfTiles / a hierarchy chart for the program

Give the name of a method and describe its purpose-

Give an example of an abstract data structure used- a linear queue, dictionary

State the name of an identifier for:

A user-defined data type

A global variable used to store a whole number

A function that returns a string.

A user-defined subroutine that has only one parameter

Explain what happens to the other items in the tile queue when one item is removed.

Why is this inefficient?

Outline how the workings of the tile queue could be improved to avoid this.

The CheckWordIsValid function uses a linear search to check whether Word is in AllowedWords.

What is the big(O) of a linear search?

What more efficient search could be used instead?

Outline how this more efficient search works.

What is its big(O)?

Explain what is meant by exception handling and how exception handling could be used in the GetChoice subroutine.

Explain what is meant by a structured programming approach.

There is a variable called Item in the method QueueOfTiles.Remove. There is also a different variable called Item in the method QueueOfTiles.Show. Explain why these two different variables can have the same identifier.

In the game, the list of allowed words is loaded from a text file. A binary file could have been used instead. Describe a difference between the way in which data are stored in a binary file and the way data are stored in a text file.

What is the difference between a value parameter and a reference parameter? Use examples from the skeleton program to explain your answer.

What is the difference between a procedure and a function?

The subroutines in the Skeleton Program avoid the use of global variables – they use local variables and parameter passing instead. State two reasons why subroutines should, ideally, not use global variables.

Describe the use of the TileDictionary and why a dictionary is appropriate

Change the distribution of letters[edit]

Change the distribution of letters so that more common letters like 'E' are more likely to be put into a hand than 'Z'

Improve the searching algorithm[edit]

To check if the word is valid the program uses linear search O(n), improve it using a more efficient algorithm, e.g. binary search O(logn)

C#:

private static bool CheckWordIsValid(string Word, List<string> AllowedWords)
        {
            /* 
             * Performs a Binary Search for Word in AllowedWords.
             */
            int mid;
            int low = 0;
            int high = AllowedWords.Count - 1;
            while (low <= high)
            {
                mid = (low + high) / 2;
                if (String.Compare(Word, AllowedWords[mid]) < 0)
                {
                    /* Word < AllowedWords[mid] so only consider lower half of list*/
                    high = mid - 1;
                }
                else if (String.Compare(Word, AllowedWords[mid]) > 0)
                {
                    /* Word > AllowedWords[mid] so only consider upper half of list*/
                    low = mid + 1;
                }
                else
                {
                    /* The word was found */
                    return true;
                }
            }
            return false;
        }

Delphi/Pascal:

function CheckWordIsValid(Word:string;AllowedWords:TStringArray):boolean;
var
  ValidWord:boolean;
  middle,low,high:integer;
begin
  ValidWord:=false;
  low:=0;

     else if(AllowedWords[middle]<Word)then low:=middle+1
     else high:=middle-1;
    end;
  CheckWordIsValid:=ValidWord;
end;

            mid=(start+end)/2;

Alternative Solution by Anon tiger:

 Function CheckWordIsValid(ByVal Word As String, ByRef AllowedWords As List(Of String)) As Boolean
        Dim Pointer As Integer = (AllowedWords.Count - 1) / 2
        Dim UpperLimit As Integer = AllowedWords.Count - 1
        Dim LowerLimit As Integer = 0
        Dim ValidWord As Boolean
        Dim Count As Integer
        Count = 0
        ValidWord = False
        While Not ValidWord
            If AllowedWords(Pointer) = Word Then
                ValidWord = True
            ElseIf Word < AllowedWords(Pointer) Then
                UpperLimit = Pointer
                Pointer = LowerLimit + ((Pointer - LowerLimit) / 2)
            Else
                LowerLimit = Pointer

alternative solution teh real swifty

    Function CheckWordIsValid(ByVal Word As String, ByRef AllowedWords As List(Of String)) As Boolean
        Dim ValidWord As Boolean
        Dim index As Integer
        index = AllowedWords.BinarySearch(Word)
        If index >= 0 Then
            ValidWord = True
        Else validword = False
        End If
        Return ValidWord

Alert the User if aqawords.txt File is Missing[edit]

Tell the player(s) if the required text file is missing

C#:

private static void LoadAllowedWords(ref List<string> AllowedWords)
{
    try
    {
        StreamReader FileReader = new StreamReader("aqawords.txt");
        while (!FileReader.EndOfStream)
        {
            AllowedWords.Add(FileReader.ReadLine().Trim().ToUpper());
        }
        FileReader.Close();
    }
    catch (FileNotFoundException)
    {
        Console.WriteLine("**** FILE NOT FOUND : aqawords.txt");
        Console.WriteLine("**** aqawords.txt does not exist. Please download.");
        Console.ReadKey();
        Environment.Exit(0);
        // AllowedWords.Clear();
    }
}

Delphi/Pascal:

The below unit can be applied to any file name and therefore is very versatile. For example, if the inappropriate words .txt file is needed then this can also be searched for.

unit checkForFile;

{$mode objfpc}{$H+}

interface

uses
  Classes, SysUtils;

function checkForFileFunc (filename : string) : boolean;
procedure checkForFileProc(filename : string);

implementation

  function checkForFileFunc (filename : string) : boolean;
    begin
      checkForFileFunc := True;
      if FileExists(filename) = False then
        checkForFileFunc := False
    end;

  procedure checkForFileProc(filename : string);
    begin
      if checkForFileFunc(filename) = False then
        begin
          writeln(filename,' cannot be successfully located... closing program');
          sleep(3000);
          halt;
        end
      else
        begin
          writeln(filename,' aqawords.txt successfully located');
          sleep(3000)
        end;
    end;
end.

The above unit's main procedure 'checkForFileStartup()', which runs the subroutines within the unit, can be referenced in the LoadAllowedWords() function so it now looks like this:

function LoadAllowedWords() : TStringArray;
  var
    AllowedWords : TStringArray;
    ListSize : integer;
    TFIn : textfile;
    Word : string;
  begin
    ListSize := 0;
    checkForFileStartup('aqawords.txt');
    AssignFile(TFIn, 'aqawords.txt');
    try
      reset(TFIn);
      while not eof(TFIn) do
        begin
          inc(ListSize);
          SetLength(AllowedWords, ListSize);
          readln(TFIn, Word);
          Word := UpperCase(Word);
          AllowedWords[ListSize - 1] := Word;
        end;
      CloseFile(TFIn);
    finally
    end;
    LoadAllowedWords := AllowedWords;
  end;

Java:

String[] loadAllowedWords()
    {
        String[] allowedWords = {};
        try {
            Path filePath = new File("aqawords.txt").toPath();
            Charset charset = Charset.defaultCharset();        
            List<String> stringList = Files.readAllLines(filePath, charset);
            allowedWords = new String[stringList.size()];
            int count = 0;
            for(String word: stringList)
            {
                allowedWords[count] = word.trim().toUpperCase();
                count++;
            }
        } catch (IOException e) {
        	System.out.println("The aqawords Text File is missing, please download it.");
        }
        return allowedWords;            
    }

Python:

import sys

def LoadAllowedWords():
  AllowedWords = []
  try:
    WordsFile = open("aqawords.txt", "r")
    for Word in WordsFile:
      AllowedWords.append(Word.strip().upper())
    WordsFile.close()
  except FileNotFoundError:
    print("The aqawords.txt file is missing, please download it", file=sys.stderr)

#First the users is prompted if they wish to add a new word, if they do then the word they type in is appended to the aqawords.txt file. The contents of the file are then loaded in the AllowedWords list. However, since I have altered the sorting algorithm in the CheckWord is Valid Function to a binary search, the words in the AllowedWords list must be in alphabetical order. Therefore a sorting algorithm is necessary, I have used a bubble sort which is quite slow with a worst case time complexity of О(n^2).

High score table feature[edit]

Add a high score table

C#:

Create a function to read from a high score CSV file, containing the players score and then the players name. The file is read and the sorted using a bubble sort, the top 5 scores and names are then outputted.

        private static void DisplayHighscore()
        {
            StreamReader FileReader = new StreamReader("HighScore.csv"); //Reads a high score csv file    
            List<string[]> Values = new List<string[]>();	//Records the data inside the file

            while (!FileReader.EndOfStream) 
            {
                Values.Add(FileReader.ReadLine().Trim().ToUpper().Split(','));  //Data is saved as score then name in a csv.
            }
            FileReader.Close();
            if (Values.Count == 0)	//If there was no data in the file
            {
                Console.WriteLine("There are currently no high scores.");
            }
            else
            {
				//Use a bubble sort to find the top 5 high scores.
                string[] temp;
                for (int write = 0; write < Values.Count(); write++)

                        {
                            temp = Values[sort + 1];
                            Values[sort + 1] = Values[sort];
                            Values[sort] = temp;
                        }
                    }
                }
				//Print out the top 5 in the list (original list was order smallest to highest - so last 5)
                for (int i = Values.Count - 1; i >= Values.Count - 5; i--)
                {
                    Console.WriteLine(Values[i][1] + " Scored: " + Values[i][0]);
                }
            }
        }

Saves the high score into this new file.

        private static void SaveHighScore(int Score, string name)	//The winners details are sent across
        {

The "Main" function is updated to allow a choice 3 to display the current high scores.

                    PlayGame(AllowedWords, TileDictionary, true, StartHandSize, MaxHandSize, MaxTilesPlayed, NoOfEndOfTurnTiles);
                }
                else if (Choice == "2")	//If 2, start game with the players start hand being predefined/ same each time- so no randomisation. 
                {

                    DisplayHighscore(); //Display the high scores
                }
...

The "DisplayMenu" method is also updated to show the user can press 3 to display the high score.

         private static void DisplayMenu()	//Used to print out the starting main menu.
        {
            Console.WriteLine();
            Console.WriteLine("=========");

            Console.WriteLine("1. Play game with random start hand");
            Console.WriteLine("2. Play game with training start hand");
            Console.WriteLine("3. Display high scores.");

The original solution stored the player score as a string type, it then went on to use a lambda function to compare these string values, which ultimately did not work (for me it did not), apologies for the crude code, but it worked for me anyway. Please do edit this if you have a better solutuion than to this

Prevent duplication of words being entered[edit]

Description of question

C#:

The have turn method was edited, such that it adds a valid word to a used word list and then checks each time the user inputs a word if it is inside of this list, if not it has not been used before and is a valid word.

 private static void HaveTurn(string PlayerName, ref string PlayerTiles, ref int PlayerTilesPlayed, ref int PlayerScore, Dictionary<char, int> TileDictionary, ref QueueOfTiles TileQueue, List<string> AllowedWords, int MaxHandSize, int NoOfEndOfTurnTiles, ref List<string> UsedWords)
{

...
                else
                {
                    ValidChoice = true;
                    if (Choice.Length == 0)	
                    {
                        ValidWord = false;
                    }
                    else 
                    {
                        ValidWord = CheckWordIsInTiles(Choice, PlayerTiles);	
                    }
                    if (ValidWord)	
                    {
                        ValidWord = CheckWordIsValid(Choice, AllowedWords); 
                        if (ValidWord)
                        {
                            ValidWord = !UsedWords.Contains(Choice); //If the word is not in the used words file, make valid choice true.
                            if (ValidWord) 
                            {
                                UsedWords.Add(Choice); //If the word was valid, add it to the used word list
                                Console.WriteLine();
                                Console.WriteLine("Valid word");
                                Console.WriteLine();
                                UpdateAfterAllowedWord(Choice, ref PlayerTiles, ref PlayerScore, ref PlayerTilesPlayed, TileDictionary, AllowedWords);
                                NewTileChoice = GetNewTileChoice(); 
                            }
                            else
                            {
                                Console.WriteLine("This word has already been played by another player.");
                            }
                        }
                    }
...

The PlayGame method is also amended to contain the UsedWords string list, this stores all of the valid words which have been played and is passed to the HaveTurn function by ref.

 private static void PlayGame(List<string> AllowedWords, Dictionary<char, int> TileDictionary, bool RandomStart, int StartHandSize, int MaxHandSize, int MaxTilesPlayed, int NoOfEndOfTurnTiles)
        {
            List<string> UsedWords = new List<string>(); //Used to store the used valid words
...
while (PlayerOneTilesPlayed <= MaxTilesPlayed && PlayerTwoTilesPlayed <= MaxTilesPlayed && PlayerOneTiles.Length < MaxHandSize && PlayerTwoTiles.Length < MaxHandSize)
            {
                HaveTurn("Player One", ref PlayerOneTiles, ref PlayerOneTilesPlayed, ref PlayerOneScore, TileDictionary, ref TileQueue, AllowedWords, MaxHandSize, NoOfEndOfTurnTiles, ref UsedWords);
                Console.WriteLine();
                Console.WriteLine("Press Enter to continue");
                Console.ReadLine();
                Console.WriteLine();
                HaveTurn("Player Two", ref PlayerTwoTiles, ref PlayerTwoTilesPlayed, ref PlayerTwoScore, TileDictionary, ref TileQueue, AllowedWords, MaxHandSize, NoOfEndOfTurnTiles, ref UsedWords);
            }

    {

          if (validWord)
          {
            validWord = checkWordIsValid(choice, allowedWords);
            if (validWord) { 
                validWord = !usedWords.contains(choice); //this just makes the valid choice true
                if (validWord)
            {
              usedWords.add(choice); //adds it to the arraylist

            }
            }
          }
...

//later on in the program

    void playGame(String[] allowedWords, Map tileDictionary, boolean randomStart, 
            int startHandSize, int maxHandSize, int maxTilesPlayed,

Display list of words (valid and invalid) used by each player at the end of the game[edit]

Description of question

C#:

Firstly a list of strings variable called "PlayedWords" is created inside of the PlayGame Subroutine, this is used to store each of the words that our played by the player. This variable is then passed to the HaveTurn method and too the Display Winners Method.

private static void PlayGame(List<string> AllowedWords, Dictionary<char, int> TileDictionary, bool RandomStart, int StartHandSize, int MaxHandSize, int MaxTilesPlayed, int NoOfEndOfTurnTiles)
{
     List<string> PlayedWords = new List<string>();
...
...
    while (PlayerOneTilesPlayed <= MaxTilesPlayed && PlayerTwoTilesPlayed <= MaxTilesPlayed && PlayerOneTiles.Length < MaxHandSize && PlayerTwoTiles.Length < MaxHandSize)
            {
                HaveTurn("Player One", ref PlayerOneTiles, ref PlayerOneTilesPlayed, ref PlayerOneScore, TileDictionary, ref TileQueue, AllowedWords, MaxHandSize, NoOfEndOfTurnTiles, ref PlayedWords);
                Console.WriteLine();
                Console.WriteLine("Press Enter to continue");
                Console.ReadLine();
                Console.WriteLine();
                HaveTurn("Player Two", ref PlayerTwoTiles, ref PlayerTwoTilesPlayed, ref PlayerTwoScore, TileDictionary, ref TileQueue, AllowedWords, MaxHandSize, NoOfEndOfTurnTiles, ref PlayedWords);
            }
            UpdateScoreWithPenalty(ref PlayerOneScore, PlayerOneTiles, TileDictionary);
            UpdateScoreWithPenalty(ref PlayerTwoScore, PlayerTwoTiles, TileDictionary);
            DisplayWinner(PlayerOneScore, PlayerTwoScore, PlayedWords);
...

The HaveTurn method is then edited such it accepts the PlayedWords parameter as ref, if the user plays a word and the word is not 0 in length (blank), then it will be added to the list.

private static void HaveTurn(string PlayerName, ref string PlayerTiles, ref int PlayerTilesPlayed, ref int PlayerScore, Dictionary<char, int> TileDictionary, ref QueueOfTiles TileQueue, List<string> AllowedWords, int MaxHandSize, int NoOfEndOfTurnTiles, ref List<string> PlayedWords)
 {
...
else
                {
                    ValidChoice = true;
                    if (Choice.Length == 0)
                    {
                        ValidWord = false;
                    }
                    else
                    {
                        ValidWord = CheckWordIsInTiles(Choice, PlayerTiles);
                        PlayedWords.Add(Choice);
                    }

The DisplayWinner method is also eddied such that it cycles through all the word plays and prints them to the console, using a foreach loop.

private static void DisplayWinner(int PlayerOneScore, int PlayerTwoScore, List<string> PlayedWords)
 {
...
Console.WriteLine("In this game the words played were:");
            foreach (var Word in PlayedWords)
            {
                Console.WriteLine(Word);
            }
            Console.WriteLine();
...

C#: Another Idea:

This method is also a 'blank tile' however this works as in Scrabble, where it allows user to choose which letter the blank may represent.
//This works like the previous idea, but directly adds an underscore, instead of using the ASCII code
public void Add()

                int RandNo = 0;

                    RandNo = Rnd.Next(0, 27);
                    Rear++;
                    if (RandNo == 26)
                    {
                        Contents[Rear] = "_";
                    }
                    else
                    {

                    }
                }
            }

// This goes within HaveTurn in the while loop.

# In comments, * denotes a wildcard in the variable name, eg PlayerFirst*
# could be PlayerFirstScore, PlayerFirstName etc.
#
# PlayerOne* and PlayerTwo* variables get renamed into PlayerFirst* 
# and PlayerSecond* variables depending on order of play.
#
# PlayerOne DOES NOT ALWAYS BECOME PlayerFirst
# and likewise,
# PlayerTwo DOES NOT ALWAYS BECOME PlayerSecond
#
# Four ~new~ variables, PlayerOneName, PlayerTwoName, PlayerFirstName & 
# PlayerSecondName, have been introduced to keep the naming constant
# at the end of the game regardless of who went first.
#
# This works with blank cards as long as the blank card ASCII value is < A.
