# implement tests for each of the methods here:
p boggle_board.create_word([1,2], [1,1], [2,1], [3,2]) #=> returns "dock"

p boggle_board.get_row(0).to_s #=> returns "brae"
p boggle_board.get_row(1).to_s #=> returns "iodt"
p boggle_board.get_row(2).to_s #=> returns "eclr"
p boggle_board.get_row(3).to_s #=> returns "take"

p boggle_board.get_col(0).to_s #=> returns "biet"
p boggle_board.get_col(1).to_s #=> returns "roca"
p boggle_board.get_col(2).to_s #=> returns "adlk"
p boggle_board.get_col(3).to_s #=> returns "etre"

# create driver test code to retrieve a value at a coordinate here:
p boggle_board.dice_grid[3][2] == "k" #=> returns true

# REFLECTION
# The object-oriented version of this code is much more readable to me.
# Instead of each method taking board and row/column variables, I can just work with
# dice_grid the whole way through.
