multiple_of_3_and_5.exs
# If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23.
# Find the sum of all the multiples of 3 or 5 below 1000.
sum = Enum.sum Enum.filter(
Enum.to_list(1..999),
fn(x) ->
rem(x, 3) == 0 or rem(x, 5) == 0
end
)
IO.puts sum
