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.

Code :


val list = for (a <- 1 to 999 if (a % 5 == 0 || a % 3 == 0) ) yield a println(list.sum)

Answer should be: 233168
