| class BoggleBoard | |
| #2) Implement your methods | |
| def initialize (boggle_board) | |
| @boggle_board = boggle_board | |
| end | |
| #1) Access multiple elements of a nested array | |
| def create_word(*coords) | |
| coords.map { |coord| @boggle_board[coord.first][coord.last]}.join("") | |
| end | |
| #2) Write a method that takes a row number and returns all the elements in the row. | |
| def get_row(row) | |
| @boggle_board[row] | |
| end | |
| #3) Now write a method that takes a column number and returns all the elements in the column. | |
| def get_col(col) | |
| @boggle_board.collect {|row| row[col]} | |
| end | |
| #4) Access an individual coordinate and call "k" in the driver code | |
| def get_coord(col, row) # note format is reversed compared to mathematics for arrays | |
| @boggle_board[col][row] | |
| end | |
| def get_diagonal_down(col,row) #feed the starting position! | |
| #@length = @boggle_board.length | |
| #ends at the end of the board | |
| until row > 3 #@boggle_board.length | |
| print @boggle_board[col][row] | |
| col +=1 | |
| row +=1 | |
| end | |
| end | |
| end | |
| #1) Instatiate a new board or object: | |
| dice_grid = [["b", "r", "a", "e"], | |
| ["i", "o", "d", "t"], | |
| ["e", "c", "l", "r"], | |
| ["t", "a", "k", "e"]] | |
| boggle_board = BoggleBoard.new(dice_grid) | |
| # BoggleBoard "holds" the new boggle_board by feeding in the dice_grid | |
| #2) Test create_word | |
| puts boggle_board.create_word([1,2], [1,1], [2,1], [3,2]) #== "dock" | |
| puts boggle_board.get_row(0).join"" #=> brae | |
| puts boggle_board.get_row(1).join"" #=> iodt | |
| puts boggle_board.get_row(2).join"" #=> eclr | |
| puts boggle_board.get_row(3).join"" #=> take | |
| puts boggle_board.get_col(0).join"" #=> biet | |
| puts boggle_board.get_col(1).join"" #=> roca | |
| puts boggle_board.get_col(2).join"" #=> adlk | |
| puts boggle_board.get_col(3).join"" #=> etre | |
| puts boggle_board.get_coord(3,2) #=> "k" | |
| puts boggle_board.get_diagonal_down(0,0) | |
| puts boggle_board.get_diagonal_down(2,1) | |
| puts boggle_board.get_diagonal_down(3,3) #why isn't this printing out? | |
| #Reflect: | |
| # I could put the join function up in the method, otherwise, this is much like the last exercise. | |
| # We had trouble understanding why our diagonal method did not print 3,3. | |
| # I would also like it to be more flexible, on any size board. | |
| # I intend to continue to work on this... |
