TJIOI is a competitive programming contest held annually by the Thomas Jefferson High School for Science and Technology computer teams. TJIOI will be held online this year, on June 11, 2022, over codeforces. The competition is open to all high schoolers and will consist of a single, individual programming round. Problems will be over a wide range of difficulty, from USACO Bronze to Platinum level. TJIOI 2022 will be held virtually from 1:00 PM EST to 4:00 PM EST on Saturday, June 11th. The contest is open to all high school students!

All competitors will need to create Codeforces Accounts if they do not have one already. Once you have created an account, you will need to join the Codeforces Group TJIOI 2022.

• The contest will be held over Codeforces.
• Join the Codeforces group here.
• Languages permitted for the contest are C, C#, C++, D, Go, Haskell, Java, JavaScript, Kotlin, Ocaml, Pascal, Perl, PHP, Python, Ruby, Rust, and Scala.
• Prewritten code can be used, as well as online resources. Competitors, however, are not allowed to collaborate with others.
