Woohoo! I'm a genius!

I am so smart...S..M..R..T!

I want my 5 minutes back.

i got the answer on the first try: who cares?

coupland -- you do, apparently

I think what's interesting about this puzzle is how easy it is for a computer. If you disallow large spaces between coins and account for symmetry, there are only 10 arrangements of coins, and any arrangement can be obtained from any other in a maximum of 4 moves, so a basic search gets the result easily. I guess abstract group theory problems is not something we evolved to do well

this guys a prick

It doesn't seem that difficult to me. Yeah, it took me 2 tries to get it, but I was looking for a trick the first time. Puzzles like the Towers of Hanoi are a lot more difficult, and software engineers often have to solve some pretty complex ones when they are interviewing for jobs. This one is very simple by comparison.

yeah, if you watch the whole thing, he is a prick. seems to me like 4 moves is enough. I got it after one showing, but took more than two minutes.

I give up. after 16 tries.

That's lame. I paused the video and tried before he showed the solution. Following his rules, I was able to get it after a couple of tries, but I did it different than he did. I solved it in 3 moves where he takes 5 moves.

since he allows inserts, it only take 2 moves:
1, 3, 5 = big; 2, 4 = small

1 2 3 4 5
4 5 1 2 3
4 2 3 5 1
