I looked at Project Euler Problem 1. Obviously you can solve the problem with the formula of arithmetic progression sum:
<URL: http://en.wikipedia.org/wiki/Arithmetic_progression>
Even and without formula, you can solve it more elegant. The solution in Python is on a line:
sum(range(3, 10, 3)) + sum(range(5, 10, 5)); #23
sum(range(3, 1000, 3)) + sum(range(5, 1000, 5)); #266333
JavaScript solution would be:
function multiples(x) {
var sum = 0, i;
for (i = 3; i < x; i += 3) sum += i;
for (i = 5; i < x; i += 5) sum += i;
return sum;
}
