i thought the author was well known for adding twists to existing problems

Love this. It's clean and very understandable - with no extra libraries.

Why should there be a difference? Do they own problems?

what is the difference between this and the project euler one

I hate this.

holy crap - how did I miss out on this lol

Very clever! Good catch that you didn't need to translate '456', as their position remains the same.

wow, it's clever

Funny dynamic programming problem to exercise with.

That is Sierpinsky (fractal) triangle, most of the entries don't matter, you should find a way to drop these spaces.
To realize this, you may examine binomial coefficients by modulo 3.
I cannot understand most of the solutions, at least from first glance, and my own solution is rather intuitive

This translation has been rejected some time ago

Rejected some time ago.

I can't wait to solve further complex programming problems like this one.

This is crazy. I love it.

Love it
