Problem 1
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 = 0
for i = 1:999
  if (i % 3 == 0 || i % 5 == 0)
    sum += i
  end
end

println("The sum is: $(sum)")
