[gcj] Re: Commented Source Code together with Contest Analysis
What could be helpful is having a bselection/b of solutions in Java, C, C++, Python, etc... made by the Google team (since they (should) look at the code anyway :-). At the bottom of the page, one [link] solution per (main) language (and people expecting LOLCODE should be able to find a fitting language among the ones proposed). -- You received this message because you are subscribed to the Google Groups Google Code Jam group.

Re: [gcj] Re: Commented Source Code together with Contest Analysis
That would be the same as seeing other participants solutions, because I don't think the person who solves the problem for Codejam is going to comment the code. One solution could be that in the analysis, they reference one of the contestants who solve the problem the way it is described in the analysis. That way, they won't have to attach any code, and you could watch the solution encoded in some language and kind of see the translation between the analysis and the actual code. In most of the contests, I've seen the submissions of the top contestants is always very close to the analysis made.

[gcj] Re: Commented Source Code together with Contest Analysis
a) That would entail question - In which language? If you say C++ I will ask - why not Python. If you say All major languages. Somebody would ask for LOLCODE. So on one hand it is a question of resources - just like you said it is not as simple as just copying some solution from contestant. If you limit number of language this will introduce bias - some would see it as approved and not approved languages for Codejam. b) Generally if you are unable to workout solution from analysis provided it means that you are trying to bite too much in one time. This means that (sadly) you are not yet skilled enough. This doesn't mean that you should feel discouraged. No, just find some easier examples in the same field and start working from simple things to more difficult ones. Or ask for help in forums. Organizers of Codejam have to strike balance between how much time they spend providing analysis and their limited resources. I don't think they should give more detailed solutions - you can't attach all Knuth's volumes to every solution. -- You received this message because you are subscribed to the Google Groups Google Code Jam group.

Re: [gcj] Re: Commented Source Code together with Contest Analysis
Good points Stanislav! But there's one point here. They already provide solution sometimes in Python! So they could keep posting solutions in this language or C++ or Java, cause it's what the majority of people here uses, and because one that programs in one of these languages is able to undestand a solution in another. The comments are what is important. I personally would choose a solution explained for a newbie to understand, than that bunch of text from Contest Analyse without a solution. Thank you.

Re: [gcj] Re: Commented Source Code together with Contest Analysis
I agree with Stanislav. I believe the Code Jam organizers would like the participants to develop a level of thinking such that giving a brief outline would be sufficient to understand the solution. If you observed, the contest analysis gives us an insight into the essence of a problem. Assuming you genuinely spent enough time trying to crack the solution to a problem, it so happens that you would missing an important detail of the problem. The contest analysis aims at giving you the key idea which will often lead you to the Aha! moment. That is probably how you improve.
