For example, in a Cartesian coordinate system the vectors (0, 1) and (1, 0) would form an orthonormal basis.
*!@# you guys. Making me wanna play VVVVVV.
I don't see the connection.
I don't see the problem either.
You have to actually play the game to understand =).
What is VVVVVV? Is it like WoW?
Yes. It's a Korean mmo with focus on open world pvp.
Wow, I was joking. That's actually the name of something?
I was joking too. It's actually a pretty sweet platformer.
Is this like the Eddie Izzard standup bit where he goes back and forth between something being true and not true about 20 times?
Sure, that sounds like fun.
What if the odd ball weighs less or more (you don't know which) than the others?
Here's what I've come up with:
I'll label the balls as 1, 2, ... 7.
1 Weigh 1, 2 v/s 3, 4. If they are equal, the odd ball is 5, 6 or 7:
1.1 Weigh 5 v/s 6. If they are equal, the odd ball is 7 (2 weighings). Otherwise, it's 5 or 6:
1.1.1 Weigh 5 v/s 1. If they are equal, the odd ball is 6, otherwise it's 5 (3 weighings).
1 Otherwise, the odd ball is 1, 2, 3 or 4:
1.2 Weigh 1, 2 v/s 5, 6. If they are equal the odd ball is 3 or 4:
1.2.1 Weigh 3 v/s 1. If they are equal, the odd ball is 4, otherwise it's 3 (3 weighings).
1.2 Otherwise, the odd ball is 1 or 2:
1.2.2 Weigh 1 v/s 3. If they are equal, the odd ball is 2, otherwise it's 1 (3 weighings).
Is this correct?
It can't be done in just 2 weighings, can it?
Is there a number of balls that ensures a neat solution like the one where the odd ball is lighter?
Funny thing is that I just made up that question. I don't know if it's hard, easy or indifferent. I was really just trolling. Great effect.
Haha. I had heard it before, though.
H5, what about
1,2,3 vs 4,5,6 with 7 on the ground. If it's equal, seven is the odd one.
If one sides sinks, you just put a,b with c on the ground. So 2 weighings
I don't get it. What are a, b and c?
Placeholders for either 1,2,3 or 4,5,6.
If a+b+c = d+e+f then g is odd
is false, with a+b+c weighing more, a = b then c is odd.
is false, repeat
Does "If 2 is false" mean "if a = b = c"?
I just found Haskell.
Nice. Have fun.
I just found Haskell.
like, the programming language?
