I will not post solutions to the problems but I will post screenshots showing that I have solved them, the entire point is that other people have to learn themselves.

I'd never post solutions for the very hard problems as that goes against the entire point of Euler.

I agree with Rick

Posting the solution ruins it

I agree with the others, posting the solution would be nasty.

What a circle-jerk.

No one cares about the answer. It's all about the method. Coming up with and sharing creative solutions is the whole point.
