When I am writing those words, there are 2002 problems on Cody. Many of them are simply wonderful. Do you remember which of them were your favorite? Vote for them!

* Write a function which returns a number of problem you wish to vote for.
* You can vote for problems created by other players.
* At first you can submit up to 10 solutions which equals 10 votes.
* When you will use 10 votes limit you will receive the opportunity to vote weekly (one vote per week, but it does not accumulate).

Other info:

* Size of your solution will be the number you submitted. It's on purpose of Trendy gathering data to make summary here.
* If you really need to be a leader, please submit 0. I don't want to favorize any problem because of its number :-)
* Please, feel free to write your memories about problems you really like. Where those most  challenging, difficult or funny? I will be really happy when comments below will become a little thread about problems worthy to be memorized and really nice ones but forgotten.
* Don't forget to _Like_ your favorite problems, if you haven't done this yet.
* Most of all: Have fun!

Temporary info (will be removed soon):

* There will be soon a plot with top 10 (or N) problems. I just have to make a trend and plot on Trendy, and I need some votes to start with.

Great idea!

James on 12 Feb 2015

Make sure you update the problem description with the requisite Trendy Plot when that gets up and running!

J.R.! Menzinger on 2 Mar 2015

Great idea, but it is quite challenging to choose only a few problems when you solved 1500+ here on Cody... ;-)

Jan Orwat on 3 Mar 2015

I'm open to proposals. Would you like something like 7 votes per week? Since it is possible to vote for one problem multiple times I would like to keep some kind of limit. Right now, when limit is reached you have to wait at least one week, but number of votes is then fixed to one, and then there is always minimum one week waiting period. Would you like it to work in cumulative way? I mean if you have K votes left, there are N votes per week, after M weeks without voting your current limit is K+N*M. Maybe that would be clearer? I look forward to your opinions.

Is this still solvable? The test suite's timing out for me.

"Steal, Share or Catch: Tournament..." by Doug Hull. An old problem, I had a lot of fun with. Recent post on Blogs by Ned Gulley about Monte Carlo approach to Game Theory refreshed my memories, so I 've started with that one.

Wonderful initiative. I would need some time to give an honest answer. So many nice old problems ...
