# Vote for Best Codechef Problems of 2016

#5
1. ASTRD : interesting 3D geometry problem with a simple but nice insight
2. QUEHEA : seemed difficult at the first sight but got simpler after analyzing behavior of graph
3. LCPMAX : nice variation of string hashing

#6
1. AMAEXPER : Nice tree problem
2. SHAIKHGN : Taught me optimization

#7

1.BGQRS : Taught me how segment tree works but I still struggle with this

#8

I will uptove ASTRD. And further throw in MGCHGEOM because I learned way too much while working on this and spent pretty much the entirety of 3 days on it. TULIPS was another one that took a long time but again taught me a lot.

#9

Thumbs Up if you want more of such initiatives.

I would Love to see Best Problems to solve to clear your concept of a specific topic

1. [POLYEVAL][1]
2. [FRIEMEET][2]
3. [KIRLAB][3]

#11

I voted for the following 3 problems (for the following reasons):

• CHNBGMT: I learnt a new lemma which was needed in order to solve this problem 100%.
• CHEFPOL: It seemed hard when I first looked at it, but the code ended up being so short and easy to write.
• BOUNCE: Hard number theory problem; even after having the right idea, I had to do lots of algorithmic and low-level optimizations to make my solution run in time (sadly there’s no editorial for it, yet).

PS: I already edited the question to assign votes to these problems.

#12

Help me with Karma, I can’t ask questions… Pretty please with a cherry on top

#13

@pkacprzak Thanks for making such discussion! I really learned new approach and strategy from these up voted problems.

#14

Great! Can you add them to the list as I suggested in the rules? That way we can keep it up to date.

#15

#16

can you add them to the problem list above by editing it?

#17

I am not getting the option to do that

#18

Can’t figure out how to edit this ? Can you help me

#19

+1 for ASTRD

#20

I am unable to locate the option to edit the post. A little help?

#21

@pkacprzak, as far as I remember only the author or someone with more than 1.5/2k karma points only can edit the wiki post and for others, even the “Edit” button is not available

#22

@likecs and others, so maybe its better if I remove community wiki tag and keep the list updated by myself?

#23

@pkacprzak, maybe removing the wiki tag may be of no use. By the way, I may also help in maintaining this list as I can see the “Edit” button

#24

@likecs ok, great, just be careful not to double-count votes
