Project Euler Problem 1
So I started solving Project Euler problems a while ago. A long time ago, actually, over a year ago. I’ve only got 31 solved but I plan to do more, much more if possible.
So here are my solutions to them, one by one.
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.
We can solve this very quickly in Python.
sum([x for x in range(1,1000) if ((x%3==0) or (x%5==0))])
Done! :-D
