Answer 2

do you guys want to solve it?

Answer 3

i already know this paper... i'll just watch you guys doing them.

Answer 4

I'm trying A2

Answer 5

I learned something called the invariance principle or something along those lines. It sounds simple. There are many problems like B2 where they do those stupid things. In that case, one should find something that remains invariant at each step, you know, a quantity that does not change.

Answer 6

Commenting so I get pinged later.

Answer 7

I think the only one I am able to do is maybe B1 rofl. Looks fun though, A4 looks neat as well mhm.
