Um, that's really easy to do in your head, there's no carrying or anything? 7,070
7 * 101 = 707 * 10 = 7,070
And computers don't brute-force multiplication either, so I'm not sure how this is relevant to the comment above?
- polotics 11mo agoI think it is very relevant, because no brute-forcing is involved in this solution.

- numpy-thagoras 11mo agoThe brute force got reduced down to fast heuristics, like Arthur Benjamin's Mathemagics.
