Problem 1:Multiples of 3 and 5
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.

  • 解答例
sum = 0

for i in range(1, 1000):
    if i % 3 == 0 or i % 5 == 0:
        sum += i

print(sum)
