# implement tests for each of the methods here:
puts boggle_board.create_word([1,2], [1,1], [2,1], [3,2]) == "dock" #=> true
puts boggle_board.get_row(1) == "iodt" #=> true
puts boggle_board.get_col(1) == "roca" #=> true
puts boggle_board.get_board #=> Nicely formated game board

# Now print out all the rows and columns of the board as strings.
# You should end up with 8 four letter words.

4.times { |i| puts boggle_board.get_row(i) + "\n"}
4.times { |i| puts boggle_board.get_col(i) + "\n"}

# create driver test code to retrieve a value at a coordinate here:
# can either use #get_board or the #[] method.

puts boggle_board[3,2] == "k" #=> true
puts boggle_board.get_letter([3,2]) == "k" #=> true

# BONUS: Creat a #get_diagonal method. Tests:
# puts boggle_board.get_diagonal([0,0], [1,1])



# REFLECT: How is the implementation different? What are the benefits to
#          using the Object Oriented approach (even if it is a bit more code?)

# OO allows for better organized code, that allows for easier changes and easier reading.

# Decided to change get_row and get_col to use array counting because create_word counts that way and I
# think it would be confusing to have one method count one way, and the others count a different way.

transpose is new to me and looks very useful, thanks. There's a method for everything in Ruby, isn't there? I don't even know why I'm typing this, there's probably a Ruby method to type it for me.
