Write a program to print the solution to the next Project Euler problem to the console in a language chosen by you.

rules

1. The problem number must be one more than the previous.
2. The next solution must use fewer characters than the previous one.
3. Ignore any time complexity requirements if needed.
4. If you think you can't advance, start over, keeping the problem number.
5. The language must be both interpreted and a general-purpose language.
6. Do not use loopholes at all.

My turn!

problem 1 (python, 122 chars)

m3 = [i if i%3==0 else 0 for i in range(1000)]
m5 = [i if i%5==0 else 0 for i in range(1000)]
print(sum(list(set(m3+m5))))
