Though that works too for solving it, but you have to start from n=1 and count up until you get the right # of equal values
 
Hmm now that you say that, lemme get another case up...
 
So what if more than one group aligns at the same time? Given 2,[1,2,3,3,3], after two seconds you'll have a group of 2 aligned and a group of 3 aligned. Does that count as exactly 2?
 
Anonymous
@Geobits Nope
 
Anonymous
That is 5 hands aligned.
 
So not only do you have to check that n values are aligned together, but that all others are distinct?
 
Anonymous
3:05 AM
That specific case would be invalid input, because it is impossible for exactly 2 hands to be aligned
 
Anonymous
@Geobits Correct
 
Oh boy :/ didn't think of that
 
K, you guys have fun with that :P
 
Now I think we're in the "uh oh" territory
 
Mini-challenge: Given a string containing -=o interspersed with single .'s, output any one of the guys who is the most awake. o.o = 100% awake, o.= and =.o = 75%, o.- and -.o and =.= = 50%, -.= and =.- = 25%, -.- = 0%.
Examples:
-.- -> -.-
o.=.- -> o.=
-.=.o.=.- -> o.= or =.o
=.=.-.o.- -> =.= or -.o or o.-
-.=.o.o -> o.o
=.-.= -> =.- or -.=
 
3:09 AM
I mean, this means that a n = 4 where the solution is 2 groups of 2 is okay then?
 
Anonymous
@Sp3000 Yep :P
 
... question needs more clarification, again D:
@Calvin'sHobbies Main site challenge please :P
 
If n=2 then I choose two groups of one hand each: 2,[3,4] -> 1 :P
 
@Sp3000 But so silly :P
but maybe
 
And that's a problem?
 
3:10 AM
That one's a little less trivial that the others, tbh
 
Fine, after french toast.
 
Anonymous
@Geobits The groups must be of size 2 or greater
 
French toast? Where?
I want it
 
In my frying pan
 
Oh damn son
 
3:11 AM
@Calvin'sHobbies I'm agreed with Sp3000. That's more like a main site challenge. :P

A hand cannot be aligned with itself
 
You don't want to join it
 
No, but I want to join you in consuming it
 
@Calvin'sHobbies Don't tell us what we can and can't do with our lives. As some philosopher probably hasn't said, "Sometimes you're the frying pan, and sometimes you're the French toast."
 
@Eridan It's just that your shoes would be melting and all..
 
Anonymous
3:13 AM
@Sp3000 Clarificated
 
@Mego In light of recent chat, I think the "invalid" example is wrong. For 2,[3,4,12] you'd have 4 and 12 aligned at 6 seconds.
 
Anonymous
@Geobits Ooh yeah you're right.
 
@Mego In light of recent chat, I propose that Mego solves this one by hand: 5, [4, 14, 36, 50, 63, 180, 210]

@Calvin'sHobbies waffles duh
 
@Calvin'sHobbies 1.) What is a Dutch baby? 2.) French toast is not a pastry
 
any MSE-dweller knows that waffles is the correct answer :P
 
3:15 AM
A Dutch baby pancake, sometimes called a German pancake, a Bismarck, or a Dutch puff, is a sweet popover that is normally served for breakfast. It is derived from the German pfannkuchen. It is made with eggs, flour, sugar and milk, and usually seasoned with vanilla and cinnamon, although occasionally fruit or another flavoring is also added. It is baked in a cast iron or metal pan and falls soon after being removed from the oven. It is generally served with fresh squeezed lemon, butter, and powdered sugar, fruit toppings or syrup. A basic batter incorporates 1/3 cup flour and 1/3 cup liquid per...
 
@Calvin'sHobbies Oh, I've had those, just haven't heard them called that.

Tim Post sent me swag (for a fun post at that), so I do not speak ill of him.
 
@Calvin'sHobbies ok
@Geobits Did he send it from the Tim Post Office? :D:D:D:D
 
@Geobits Tim Post is indeed Lord of All Swag, but here on SE telling someone that they hate fun is a compliment. :P

@AlexA. Pancakes are like french toast without the egg. They're an inferior subset.
 
@AlexA. If you wanted votes for pancakes, you should have voted for pancakes :P
 
@Geobits Also in light of recent chat, 2, [3,4,12] has a solution after 4 seconds actually

@Mego My French toast has no eggs. I don't see the issue.

They're nobody's first choice, that's why they have no votes.

@Doorknob yusss
Every time I have waffles, I fill all the pits with syrup.
 
Me too! I always have to make sure to get at least some syrup in every one. Otherwise the integrity of the entire meal is undermined. :P
 
Don't forget the butter :/
 
I usually don't eat waffles with butter.
 
3:23 AM
The swirling mixture of butter and syrup is what goes in the pits if you're eating them correctly.
 
I eat waffles with peanut butter
 
Off-topic: tentative prediction of start of Winter Bash on December 14.
in Tavern on the Meta on Meta Stack Exchange Chat, 1 min ago, by SmokeDetector
@NormalHuman HATS ARE AWESOME. Winter Bash will begin in 23 days, 20 hours, 36 minutes and 59 seconds. :D
 
@Mego It has batter, the batter just doesn't have eggs.
 
@Rainbolt That's probably very good, but I'm going to insult it on general principle because it's different from what I do.
 
3:25 AM
@Rainbolt Don't
 
Too late
 
Interesting...
 
Options:
Throw it away
Eat it
 
Please tell me that isn't chunky.
 
It's especially nice when the waffles is hot enough to make the peanut butter runny (no, not chunky @Geobits)
 
3:27 AM
Oh, ok. In that case it looks pretty good ;)
 
Anonymous
@Rainbolt Eat the shit out of it
 
Hot peanut butter doesn't stick to the roof of your mouth nearly as much as cold peanut butter
 
But still, see my previous comment about differentness.
@Mego Ewwwww.......
 
@Rainbolt Cold peanut butter?
 
If you fold it in half, you can hide the peanut butter. We can hide our differences.
 
3:28 AM
@Rainbolt Except you stole that picture from wikihow.com/…. :P
 
@AlexA. I'm using cold to mean "not hot" in that sentence.
 
@Doorknob You sure they didn't steal it from him?
 
Oh, okay. Peanut butter should never enter the refrigerator under any circumstances.
 
@Doorknob My waffle looks exactly like the one on Wikihow, obviously.
 
i eat peanut butter on pancakes but it doesn't seem like it would be as good on waffles
 
3:29 AM
@Rainbolt Ah, I see. Okay then, nothing suspicious here.

@AlexA. no it's Firefox
 
@Doorknob Oh. Okay. I don't use Firefox.
 
@Mego btw in case you're wondering, I made this test case especially because you mentioned 360/x*n%360, and if I'm correct I don't think that approach works
 
I heard that Doorknob uses Internet Explorer for Linux.
 
Based on the fact that you got 315, I think I might be right
 
3:41 AM
@AlexA. I sincerely hope that doesn't exist
 
@Geobits i can't find a source for this, everything is backing up my previously-held belief that aeris was a mistranslation that they fixed
i meant to reply to the other message oops
 
Anonymous
@Sp3000 360/x is the angular velocity of the hand whose rotational period is x. 360/x*n gives you the total number of degrees traveled by the hand after n seconds. 360/x*n%360 gives you the displacement in degrees. I don't see how that doesn't work.
 
When the hands don't align at a whole number of degrees

@undergroundmonorail Meh, they originally changed it in Kingdom Hearts IIRC. Saying it's more right in a related game than in the original makes no sense to me, but whatever. I don't get upset or anything when people call her Aerith, but she'll always be Aeris to me.
 
Not sure if that'll affect anything though (might not)
 
エアリス still even sounds like Aeris IMO.

If the requirement was rational solutions, it would be a more linear set
 
Rational? Aren't all solutions rational?
(Perhaps you mean integral?)

But because the requirement is integers, it takes a lot of revolutions for 3 to be aligned and an integer amount of time to pass
