Letter to the codechef admin.

@admin, while i read many editorials on codechef , i found it hard to understand just by reading. but when i find the editorials on Youtube for some well known algorithms, they are very easy to understand. It will be greatful if you start uploading editorials in video form or you can allow other codechef users to upload the videos related to editorials who have already solved the questions in a contest.this can save our lot of time reading and interpreting the editorails line by line..!!(you can also think to make your own channel on youtube for explaining the editorials) I hope my point is clear to you. Thank you..!

You might be facing this issue because you have not solved enough no. of easy questions and directly approaching the harder problems. May be I am wrong, but I would suggest you to go ahead step by step rather than solving very hard problems directly. This might lead you to the frustration.

Hey All, Thanks for the kind suggestion. We will love to put up video editorials. However, at present we are running a rather packed schedule, which makes it pretty tough to squeeze in such a huge task. If anyone of you are interested in taking up the task, you are most welcome. You can write into us at: and we can take it further.

I was just thinking of this and you came up with this post. Yes, It would be great and easy if Codechef posts video editorials.

Uploading the videos on youtube and providing the link of the video in the editorial would be fine.

I am also facing same issue ..Editorial very dangerous to understand...

uploading videos at codechef editorial on codechef site become burden on this site.

before you , one user also raised this point , they had answered it will become burden to handle so much heavy data ..

I think It is not good choice because it will slow down performance codechef's site itself as it will contain heavy data.

I think they should make own youtube channel or they can link some tutorial or channel which are already exist and directly related to problem specifically

Or one thing they can do they should provide some platform where users also can make his own video editorial and provide to codechef admin which they find best link that editorial only(video) with proper explanation and they also can provide some karma for those users who will provide good editorial to make interesting and competitive this things also

if anyone has other idea please share will help of many of many users...(

(both of us too..:P)

happy coding

Yes, video lectures are easy and fast to understand, but who will do the video lecture editorial, Video lectures for some algos like KMP,Tries are fine, I dont think its possible to have a video lecture for every question, and to store them all in their server,and Ediotrialist may not have time for it and some problems editorials have lots of links and pdf pappers to be studied .

We face technical glitches often, video tutorials would just add to it. Isn't it better that u see the tag,research about it, try the problem again,if done then good and well,else read the tutorial.If u stil dont get it then go for video tutorials(prefer it the least). Dont go easy on yourself,u never know what u r capable of... :)

@admin If you do video editorial, along with the video, don't forget to post the written editorials too. Some of us (like me) don't really have fast Internet connection to stream or download video. Plus I find reading more easy to understand than someone teaching.

we are not saying remove written editorial ..

we are saying please link video tutorial link too..

(26 Aug '15, 10:57) rcsldav20175★

don't be worried @dragonemperor...!! we are asking for both type of editorials..!! textual as well as video.. :)

(26 Aug '15, 14:19) va1ts7_1003★

It won't hurt; however, I don't see reasons to think such thing is really needed.

First of all, usually these videoeditorials aren't saving your time :) You need only a few minutes to read short editorial, and much more time to watch a video where same things are described in detail. By working on editorial by yourself for same time you should be able to reach same results.

And if it looks that you aren't - there are several possible reasons. It is possible that editorial is bad. From my experience, such happens quite often, but still most of editorials at CodeChef have a pretty good quality. It is possible that you are not capable to learning for some reason. That's bad news for you. People all over the world are fine with learning from editorials - users at sites like CodeForces are fine with learning from editorials, why can't you?.. And the last possibility is - you are simply lazy. Lazy to work on it and learn new things. In this case videoeditorial wouldn't help you much. You'll feel like you learned and understood things better, because they were explained detailed, but in a lot of cases it will be a wrong impression.

Rarely there are things which can be presented in video but can't be presented in text editorial (like some dynamic illustrations). Also there are some people who pathologically can't grasp one form of representing of information (like text) but are doing much better with some other form (sound, video, illustrations). But in most cases it doesn't make much difference.

These video need somebody to perform that videoeditorial, they also need storage, you need good connection to watch them... Once again, there is nothing really bad in your idea...

If you find editorials at other sites good, while CodeChef editorials are constantly bad for you - maybe it should be a feedback for CodeChef editorialist - they should change something in the way they are presenting ideas and solutions. I don't face such troubles, but if there are lots of people saying same thing - it should be a sign for CodeChef team. If all text editorials are hard for you - I have bad news for you; you should start working of improving your learning skills, because if you aren't capable on learning - other people have huge advantage over you, and you'll face hard times qiute often.

@lebron.. first of all we all are not lazy..!! and second , there are various kinds of people on earth, some understand directly by reading the books, some understand after the lesson is taught in class(kind of video lecture in real life). May be u are of first caeogery , but it dosen't mean that we peoples are slow or we have less mind in our head..!! we find reading things very boring and sometimes abmiguous..!! hope u get it.

(27 Aug '15, 20:34) va1ts7_1003★

That sounds funny. Anyway, I explained my point - and now, after your response it is pretty clear to me that you are probably not going to show good results in competitive programming - because you find learning new things "boring" and you aren't willing to put your effort into it. Let's hope that's wrong impression. Feel free to find my answer arrogant or harsh (and it is almost definitely unpleasant for you, that's obvious - nobody like reading such things) - but I simply explained my point of view, according to my own experience.

(27 Aug '15, 21:36) lebron7★

You know, sometimes harsh words help :) And when they don't - I hope it doesn't hurt you much. Think why such question was never raised at sites like Codeforces. My point isn't about this idea being bad. No; idea is quite good; it can make things better, sure. But the point was about other thing - the way you described everything says a lot about you, and there are bad signs. You should start with learning to learn first of all.

(27 Aug '15, 21:45) va1ts7_1003★

@admin I too believe that this is a nice suggestion. I feel that as codechef has expanded to a great extent in recent years and it will be great to have editorials for the future contests in form of videos. This will really facilitate learning of large number of users and the ultimate aim of codechef. Hope this comes up soon.
