FP Homework 1 extension

1 - Chess position

Implement the function move which has 2 arguments of the type Result (position A and position B). Function result type is Bool, It is True if it is possible with one chess piece move get from position A to B, false otherwise.

move :: Result-> Result -> Bool

2 - Ticktacktoe

Implement the function winner which has 1 argument - play-filed. It will return Bool indicating that on of the player have more then 4 pieces in a row, column or diagonally.

winner:: Result ->

3 - Maze

Implement the function maze which has 2 arguments. First argument is a list of strings representing a maze row by row from top to bottom ('*' - wall, ' ' - empty square, 's' - starting position). At the beginning we are at position 's'. Second argument is list of directions ('d' - down, 'u' - up, 'l' - left, 'r' - right). Each letter means move by one square in the given direction and on this new square character '.' is placed. Print actual state of a maze.

maze :: Result -> String -> Result 

sampleInput = ["*********",
               "*s*   * *",
               "* * * * *",
               "* * * * *",
               "*   *   *",
               "******* *",
               "        *",
               "*********"]

Prelude>pp(maze sampleInput "dddrruuurrdddrrddllllll")

*.*.*.* *
*.*.*.* *

4 - Minesweeper

Implement the function minesweeper which has 1 argument of the type list of strings. The strings represent play field row by row from top to bottom ('*' - mine, ' ' - empty square). Print play field in a way where mines will be represented by '*' and on each square not containing a mine will be a number - count of all mines directly adjacent to this square (it can be adjacent vertically, horizontally or diagonally).

minesweeper :: Result -> Result
sampleInput = ["       ",
               " *     ",
               "    *  ",
               "   *   ",
               "      *",
               "***    ",
               "* *    ",
               "***    "]

Prelude>pp(minesweeper sampleInput)

1*11110
1122*10
001*221
233211*
***2011
*8*3000
***2000

5 - Ships

Implement the function ships which has 2 arguments. First argument is a list of strings representing play field of one player row by row from top to bottom ('o' - square containing a ship, ' ' - empty square). Second list contains coordinates of squares attacked by second player. Print actual state of a play in the way where every row and column will be labelled by its number or letter, 'o' will be square with ship not attacked yet, 'x' square with ship already attacked, '.' already attacked empty square, ' ' empty square not attacked yet. You can consider that the size of play-field is 10x10.

ships :: Result -> [(Char, Int)] -> Result
sampleInput = ["  o    o  ",
               "      ooo ",
               "   oo     ",
               "          ",
               "          ",
               "     o    ",
               "     o    ",
               "     o    ",
               "          ",
               "          ",
               "  oooo    "]

Prelude>pp(ships sampleInput [('a',1),('d',1),('d',2),('c',1),('b',1),('e',1),('f',1),('g',1),('c',7),('c',10)])
