# Game of life

# Goal is to have a 2D list that looks like:
[ [false, false, true, false, false],
  [true, true, false, false, false],
  ...
]

# data is a list of coordinates {row, col} where {0,0} is the top-left origin
data = [{0,1}, {2,3}, {3,4}, {4,4}]

# Solution
for i <- 0..4 do
  for j <- 0..4 do
    a = for {^j, ^i} <- data do
      true
    end
    case a do
      [] -> false
      [_] -> true
    end
  end
end
