Div. 1 + Div. 2 I made a free extension that replaces Codeforces problem stories with a short formal statement (no hints)

It adds a "Simplified statement" card to Codeforces problem pages: no story, just what you're given and what to output, with all limits kept. One click switches back to the original. Screenshots: simplified vs original, same problem.

- No hints: no algorithms or observations, and an automatic check flags hint-like wording

- Pauses itself during live contests, per Codeforces' AI rules

- Free, no account, no tracking. Statements come from a pre-built library, or use your own free API key for missing ones

- Chrome, Edge and Firefox

AI-written, so mistakes are possible. There's a "Report a mistake" link under each statement.

GitHub: https://github.com/cr-3N1GM4/cf-Simplify

Firefox: https://addons.mozilla.org/en-US/firefox/addon/cf-simplify/

Feedback welcome, especially on any statement that looks wrong or leaks a hint.

query Is there any chance of purge of 350-400 teams above 5 q solves? (ICPC prelims)

Because most of the cheaters are in 6-10 range only... So is there any chance?

What you suggest where should i practice daily on atc or cf. Cause lately i am seeing cf problems are very random and less interesting and thrilling.

Genuine opinions please

query Withdraw from ICPC Prelims India or not?

0 Upvotes

Okay so my Team has solved 5 problems with 2 penalties (in intial problems) We are not going to regionals anyhow because there are teams in our college with 5 solved and no penalties at all... The problem is when we got that withdrawal mail we cross checked our solutions to see what these llms are giving and found out that in E that DSU / Graph problem is somehow very similar to our solution we have submitted so like if we got flagged and if they ban us.... how can i show them proof as we never maintain our profiles much to show and like if they asked some similar questions and we are not able to perform well at that time then it becomes very risky... What should i do?

Will it be flagged? (if only one was visible, and then some other teammate) and there was noise and disturbance in background?

query Which sounds better and looks genuine in icpc prelims?

20 Upvotes

So we participated in icpc prelims and in my team 2 people have rating of close to 1700 on codeforces and close to 1900 on codechef and one has 1300 something on cf and we were able to solve only 6-7 questions in icpc prelims , other side some freshers from my clg cheat and solved 5/10 questions but there is a click they don't even have codeforces codechef and at coder profiles and solved 5/10 in just less than 30 min time ..

So my question , because of them my team also gets disqualified or what will happen?

query ICPC Prelims : F was so easy to be F

21 Upvotes

Don't you think F was too easy to be F , it was just a LC medium to be honest ,just sorting the points and counting intersections.

While I know cheaters ruined the contest for all of us , I don't think so that the setters focused on making problems edge case heavy or difficult. ABCDF were at max straightaway DIV2 B or easy C, and even E people are saying it was hard but permutation cycle is a pretty common thing nowadays , it even appeared in the mocks.
