@Razor "Goldstein expert" That's a strange compliment =P

But yeah, he seems to be awesome at classical mech

@JohnRennie I need a bit of help with this algorithm question in Java. According to me, the outer loop runs $n$ times, and for each of those $n$ times, the inner loops runs $(n-i-1)(n-1)$. So the number of array accesses should be $\sum (n-i-1)(n-1)=\frac{n(n-1)^2}{2}-n(n-1)$. Also, each time the array is accessed thrice. So the answer should be an order $3n^3$. But that is wrong. I am not being able to figure out why :/

Oh, I think they are taking the $\frac{1}{2}$ also into account

That's strange

@JohnRennie How are you getting the $\sqrt{n}$ ?

$log$ ? But how?

@JohnRennie I think that is k*2 written

The imgur ruined the pic quality

Anyway

Yeah, I think that is one point

We can get something like lg(n)....but I'm still thinking

@JohnRennie :P

Don't you wake up at 4 or something ? XD

Umm, I think I'm getting it.....k=1 ---> 2 -----> 2^2 ------> 2^3 ---------->till we reach near to n

@JohnRennie Oh, no prob!

$lg(n)$ denotes the power of $2$ reached before the innermost loop terminated

woohoo :D I get it!

Hi @ATaco. Nice name :D

@ATaco Most people here are also not physics nuts except JR perhaps :P Most are mathematicians. And a few people like me who are neither visit this room everyday. :)

@JohnRennie Don't worry. I still remember that you're half geek half nerd but complete nuts. ;)

:D

@Sid @PrathyushPoduval @Kaumudi.H @Yashas @BalarkaSen Happy Independence day guys :D! (Though I'm happy only coz....one extra holiday :P)

Happy Indipendence Day! :-)

Also, hi, everyone! :-)

Hi :) How's it going?

You're in Kerala or at home?

@Blue It's going OK, thanks :-) And you?

@Blue Nah, holed up in my room, as always :-P

Did you go back home?

@Kaumudi.H Nope. I'm in Kolkata only....I don't want to waste one free day travelling :P

Haha, OK :-) What are you up to?

Nothing much. Just doing solving algo problems :P (And homework stuff)

Cool :-) I've got records to complete :-( And again, I haven't eaten anything substantial in over 24 hours.

@JohnR: That USB adapter is arriving today, I'm told!

Fortunately we have a few canteens inside campus. They have good food.

You're luckier than I am :-(

@JohnRennie Lol, certainly not, but I can use them to watch lectures etc.

@JohnRennie OK, actually! :-o

Oh...you're participating in a race! When is it?

Ooops

How was it ? =P

@JohnRennie Actually, no, not in Kochi.

In Chennai, YEP!

BTW, I have dropped out of college to take the position of Permanent Sweeper Of Room.

@JohnRennie :-( I do, yes, and my roommate hasn't even offered to do it once!

@JohnRennie Probably, yes, but like I said, I'm not much of a runner.

@JohnRennie Even more, somehow! And ALL OF THE HAIR!

@Blue :-P It was alright. Exhausting, as expected.

@Kaumudi.H Just stop doing it.....or ask them directly!

@JohnRennie We are two girls sharing a very small room.

lol

@JohnRennie x'D Great idea!

However, I doubt if she'd notice; even if I did ask her, she'd probably be rubbish at sweeping.

In the two weeks that we've been sharing this room, she hasn't made her bed even once! Her side of the room always looks like it has just been through a tornado or something.

@JohnRennie There is no need to ask: they do the same thing. Sometime, a bunch of students rent an apartment but hopes of that happening have dwindled.

Hehehe :-) True.

Gah, and as I type, I am also currently doing my laundry :-(

Actually if your roommate is like me, then she wouldn't bother even if you gather a mountain of dust on her side of them room. I just never notice dust until someone points it out to me. You should see my room once :'D. (So perhaps you should talk to her directly and I'm almost sure that she won't refuse)

There are, but none of them are as near to the college as this one.

I am also delighted to inform you that I haven't eaten in over 24 hours.

@JohnRennie Well, yes, but, hmm...

Order something :/

There is time to think about it...

@Blue From where?! There are no good restaurants nearby.

@Kaumudi.H There are websites like Zomato and all. Also dominoes, pizza hut etc...For cheap food there must be some home delivery service around

I do have a bunch of digestive biscuits here somewhere...

That sounds bad :(

I present to you my amazing to-do list of amazing:

zomato.com/kochi/order-food-online

@Kaumudi.H wheeeewwwwwwwww

@JohnRennie Haha :-)

Carpentry Workshop I suppose

@Blue Hehe, THANKS! :-) Man, you are all much kinder than people I have come to know here. I wish this place could be a third space in which I live all the time while doing all of the regular things I do.

@Blue Lol, no, @JohnR: Electrical lab.

@JohnRennie I'm in EE but I still have a semester of carpentry and fitter workshop :'D (Don't ask me why! I don't know)

Even the CS guys have it I think

@JohnRennie lol. Or maybe an important skill when you are pissed off at someone and have an axe nearby.

We literally learn how to saw wood and join them in different ways

"satisfying". Sure. We treat the class as a 4 hour long break from studies during weekdays. =D

It's fun for sure :P

Went down to collect my parcel AHA, it has arrived!

@JohnR: And it works!

Yup!

@Kaumudi.H My situation is similar to yours. My classmates are mostly boring. Several of them already got involved into college politics. Meh.

Hehe, I spent quite some time this morning singing this out loud but my roommate wasn't here to witness the amazing performance; she's gone to her cousin's place for two days.

I got removed from the class whatsapp group for refusing to sign a silly petition. Not that I care. :P

Few students are nice though

@Blue What?

Oh, man, that sucks :-/

My classmates are relatively nice and all but like I said, they aren't particularly kind, if you know what I mean. Oh, well.

@JohnRennie Hehehe :-) This weekend, she spent two days listening to the same song on repeat!!

I could hear it through her headphones and I was baffled as to how she could it. It's not even a good song!

Oh, hi, there @Balarka :-)

Always.

@Kaumudi.H It was a petition to a newspaper company which published few over-exaggerated articles about an ongoing issue in the college (basically the state government wants to look after after the placements but the student union doesn't want so). The newspaper stated that "ongoing protests, studies on hold". They were making a petition against the "studies on hold" part. I felt it was silly to bother about such silly issues and didn't sign it.

^ Also true...

@JohnRennie Yeah, that's true. I didn't expect such a retaliation though.

Anyway, this incident revealed to me the ones whom I should make friends with and the ones I should avoid.

@BalarkaSen Scroll up a bit ^ I wrote it

@JohnRennie :-)

Gah, I want to cut off all my hair again.

@BalarkaSen lol :'D They're ready to join protests at the drop of a hat anyway...

Our university has become a religion or something

They can't tolerate anything said against it

Anyway, I don't care much. I have made a couple of good friends here.

I prefer a few good friends rather than hundreds of useless ones.

@BalarkaSen yeah

@Secret Same here :)

Update: Spilt a bunch of oil on my floor whilst attempting to oil my hair.

@JohnR: ^ Case in point, really.

@BalarkaSen Wow, aren't you strong with ur insults :-P

@JohnRennie Ah, hey, so those pictures on your Fb page, are they from that time?

@JohnRennie No, there's another one of you leaning against a wall or something, IIRC...

Hmm, so exactly what do u mean by long?

That's it, I've decided that I'm going to cut my hair way short when I go back home next month.

Hang on.

@JohnRennie Wow!

Taking too long to load...

You were wearing a blue shirt(?)

@JohnRennie Yeah? :-/ Hmm...

@BalarkaSen :-)

Wow, and now I'm imagining you completely differently :-P

Argh @JohnR: It's in that motorbike album!

@JohnRennie ...how did you find him on Fb?!

@JohnR: Been looking for that picture and HEY, I think I found a picture of how you looked about 5 years ago!

Haha, yeah, that is what I found! :-)

Used to?

Ah.

BTW, @JohnR: You weren't kidding about being thin :-o

@JohnR: I AM LOSING IT! Can you please send me a link to that particular album? _/\_

Not the one I'm looking for, not the blue shirt one.

:-( TAKING TOO LONG TO LOAD!

@JohnRennie YES!!

THANKS!

@ACuriousMind Omg! :-o Wow!

@JohnRennie Yeah, that's not long at all, sorry :-P My bad.

I gotta say, it is a little strange, seeing you all as you are/were :-) Can't quite say why.

And I strive not to have hair everywhere.

OK, must get on with my day, now that my laundry is done; will shower and try and find something to eat before I start those records :-/

Wokay :-)
