# U2.W6: Create a Bingo Scorer (SOLO CHALLENGE)

# I spent 3 hours on this challenge.

# Pseudocode
#initialize the class with a Bingo Board
#method to check for winner, print "BINGO" if the board meets the conditions of one type of winning board
#horizontal board method
#
#if one subarray of the board has 'x' in each slot, BINGO
#vertical method
#if each sub array has one 'x' in the same index position, BINGO
#right-to-left method
#check first sub array for an 'x' in first index position
#second subarray for an 'x' in second index position
#third subarray for 'x' in third index position
#fourth subarray for 'x' in fourth index position and fifth subarray, 'x' in fifth and final index position
#left-to-right
#reverse logic of the right-to-left method



# sample boards

# horizontal = [[47, 44, 71, 8, 88],
#               ['x', 'x', 'x', 'x', 'x'],
#               [83, 85, 97, 89, 57],
#               [25, 31, 96, 68, 51],
#               [75, 70, 54, 80, 83]]

# Initial Solution

		vertical_win

            	@bingo = true
        	end#if
    	end#board.each
	end#horizontal_win

#print "WINNER" for a board with 5 vertical x's in same index slot of nested array
	def vertical_win #will print all 5 x's
		board.each do |row|
			row.each do |element, index|
				if element == 'x'
					@bingo = true
				end#if
			end #row.each
		end #board.each
	end #vertical_win

#print "winner!" for diagonal right to left THIS WORKS

	r_index = 0
	c_index = 0
	board.each_with_index do |row, r_index|
		row.each_with_index do |number, c_index|
			if number == 'x'
				r_index += 1
				c_index += 1
			end #if
			end #row.each
		end #board.each
		@bingo = true

end #right_to_left

end#left_to_right

end #class


# Refactored Solution


#print WINNER if each element of a subarray includes 'x' IT WORKS
# def horizontal_win
#     @horizontal.each do |subarray|
#         if subarray.include?('x')
#             print "WINNER"
#         end
