Hello, Codeforces! & Happy Chinese Teachers' Day!

We (OICon Team) are so excited to invite you to take part in OICon Round 1 (Codeforces Round 896 (Div. 1) and Codeforces Round 896 (Div. 2)) which will start on 10.09.2023 17:05 (Московское время). You will be given 6 problems and 2.5 hours to solve them in both divisions.

  • Please notice the unusual starting time!
  • One of the problems has two versions but their statement are not exactly the same, which means that you can't pass the easy version using the code of the hard version. However, you can only make hacks when you pass both versions.
  • There will be $$$0$$$ interactive problem in each division so you needn't read the guide for interactive problems.
  • Score distribution:
    • Div. 1: $$$500-(500+750)-1000-1750-2500-3000$$$
    • Div. 2: $$$500-750-1250-(1250+1500)-2500-3250$$$

The problems were authored and prepared by Error_Yuan, duck_pear, programpiggy and me.

Good Luck & Have Fun!
