Problem #1

Multiples of 3 or 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.

Solution (by Rust)

fn main() {
    let mut ans = 0;

    for i in (0..1000) {
        if i % 5 == 0 || i % 3 == 0 {
            ans = ans + i;
        }
    }

    println!("{}", ans);

}
