Bingo Winner

Bingo is a game where players are given a board of numbers.

Provided a bingo board, determine if the board is a winner.

Numbers are called, and players fill out the matching numbers on their board.

A board is a winner if it has any row, column, or diagonal completely filled.

For example, let’s say we have an empty board like so:

[
  [nil, nil, nil],
  [nil, nil, nil],
  [nil, nil, nil],
]

We’ll mark matching numbers using "X".

A winning board would look like:

# example win on row
[
  ["X", "X", "X"],
  [nil, nil, nil],
  [nil, nil, nil]
]

# example win on column.
[
  ["X", nil, nil],
  ["X", nil, nil],
  ["X", nil, nil],
]

# example win on diagonal
[
  ["X", nil, nil],
  [nil, "X", nil],
  [nil, nil, "X"],
]

Create a BingoWinner module below with an is_winner?/1 function. It should determine if a board is a winner and return either false or true.

board = [
  [nil, nil, "X"],
  [nil, "X", nil],
  ["X", nil, nil],
]

BingoWinner.is_winner?(board)
true

Enter your answer below.

defmodule BingoWinner do
  def is_winner?(board) do
  end
end

Utils.feedback(:bingo_winner, BingoWinner)

Play Bingo

The Bingo game will now use integers instead of "X" and nil.

The Bingo game will take a list of called numbers and a board.

board = [
  [3, 2, 5],
  [1, 6, 7],
  [4, 8, 9],
]

called_numbers = [1, 2, 3]

Bingo.is_winner?(board, called_numbers)
false

called_numbers = [1, 3, 4]

Bingo.is_winner?(board, called_numbers)
true

Enter your answer below.

defmodule Bingo do
  def is_winner?(board, called_numbers) do
  end
end

Utils.feedback(:bingo, Bingo)
