I solved it like this:
The numbers are x, x+1..., x+10 = 11x + 55. One is erased therefore 10x + 55 - y = 2012. 10x - y = 1957. We know X is whole so we need a number between 1957 and 1967 that divides 10 and that is X. 1960 so X = 196 and therefore y = 3. Answer is X+Y = 199.
I think a school student can do this math manually. The hardest part is the sum of the first N(in this case 10) numbers and then finding the divisor. Yes there might be a better solution.
But I think a kid would think up a brute force algorithm like this and it is easier for small N. The computation is only in O(N) complexity haha. And if an answer exists it will always be found - so it is a real solution. Might be the first algorithm you write if you are tasked to do this with software.
It naturally grows due to long running transactions because the vacuum process cannot clean dead tuples that a transaction can "see". Though more aggressive vacuum settings might solve this problem.
I remember it by first remembering that it is possible to not provide the destination (ln /.../file) to create a symlink with exactly the same name in the current directory. So it has only 1 required argument which always has to be first.
I think that most free to play games where the priced items are only cosmetics don't try to addict you to buying. Competitive games can never put any pay to win aspect in their pricing model - League of legends, CS GO, Dota, Overwatch.
Weirdly though competitive games in the end do make you buy somehow. Those games are ridiculously addictive to the gameplay itself and somehow they have huge player bases that stick for a long time. From my entire high school 2 years ago - 50% of the boys were addicted to playing some of the top free to play titles. When you put down thousands of hours in a game spending cash on it becomes very normal.

That's an uncomfortable idea - growth of a nation being dependent on a few people working their ass off. Like sacrificial lambs. Though almost all of these people probably do it willingly.
That's a very interesting statement. Could you share some more information about what events in history or research in "evolutionary biology" suggest this ?
I don't know where to start searching from for this information...
