Problems of CSP(China) Sharing & Discussion Hello codeforces! CSP-J/S(Certified Software Professional-Junior/Senior) of China ended. CSP-J/S (or you can say NOIp ,but it has been dead) was held by OI rules. In OI rules, every problem has the same score distribution $100$ points. In one problem, there is several testdatas (like $10$ ,$20$ or $25$). Every testdata has the same score distributions. Once you pass a testdata, you can get the score. You can submit your code during the contest, but can't see the result. The organizer will judge all the programs together after contest. I'd like to share the problems of CSP-S here! Hope you guys enjoy. Don't mind my poor English, I spent a whole afternoon translating. <spoiler summary="D1T1 code"> $\bf{D1T1\ Gray\ Code\ 1s\ 256MB}$ $\bf{Statement}$ _Gray Code_ is a special permutation of $n$-bit binary strings ,which requires adjacent strings have **exactly one different** bit.

About the Universal Cup, the Semifinals, and myself... Hey'all!

This contest will be a part of our Finals Team Selection, which the detailed rules and announcements will be published later next week. --- Now for some extra context, if you're interested. Last week, we hosted the [last online stage](https://codeforces.me/blog/entry/143954) of The 3rd Universal Cup. After that, I posted a [feedback form](https://docs.google.com/forms/d/1g5Txhiirh_lRsvGfkYWRozu0WDDGK31IAXjB7VgeVoM/edit) on our discord server. I received lots of thoughtful responses (P.S — it's still open, so feel free to fill it out if you haven't yet!). I've read through all the feedback, and I'd like to share a few thoughts. ### On the Number...

It paints a bad picture about myself whoever visits my profile.<br> also I can make a fresh new account and starts using it but in that case I have to loose all the progress and the graph of rating.<br> Also I am fearful about China. I am into IT and If in any case I have to travel internationally or If I have to go to china in any case I could be in trouble.<br> I have made those comments 2 years back at that time I was a kid. now Iam more mature and regretting about making those comments and they are stuck with me for my entire codeforces journey with my account.<br> <h3>Why there is no option to delete your comments.</h3> <br> I want my account to be clean. Let me tell you I ha...
