The Daily Coding Question blog! Tips for competitive programming
By vladcainamisir, history, 3 years ago, In English

Hello Codeforces!

As some of you may remember, I posted here about The DCQ, a free email service which sends you a problem every day of the week and also it's explanation and sourcecode.

We have 270 users at the moment, and want to know your feedback, so we can tailor the problems to your needs.

Also, we have launched our blog! We will post weekly articles regarding different topics.If you want to see a specific article, drop a comment! The first article is about improoving at competitive programming!

For the ones that haven't signed up yet, please do so and tell us what you think! Remember, we will reach full capacity at 350 users( after 350 users, we won't be able to afford the email service).

Update: We have reached 350 users, and from now on, we will have to introduce paid subscriptions. You will have to option to invite 3 friends for a free month with most of the benefits, or pay $3.49 if you don't wish to do so.

As a bonus for all your support, we will extend the free plan for the first 400 users, after which the referral system will be used!

If you could provide the link to the problem where we could submit and test our solution it would be great.

    That is a great idea! Thanks! We will release our code judge but when we send you problems from CF we will include the link.

Can you please make a blog on small to large trick. I have seen some blogs on codeforces but none of them explains it clearly.

      I know I am not capable to solve this problem right now. But see this problem. It can be solved using convex hull on tree along with small to large trick. I am just curious about this trick.

    We will try! I think that's a really advanced topic for most of our users but we will try!

Also, u might wanna include the future code judge in your free plan instead of the paid ones. If possible, do consider it.

    We will try, but the API we are going to use for the code judge is not free, so if you want to test your solution, you will have to buy a subscription.

I'm confused, you want people to pay for a subscription to receive problems?

    You receive the problems for free, but in order to see the solutions you will have to pay a monthly fee and also get acces to the code judge and many other features.
