Greetings from RECursion!

We are excited to announce the next session of RECollect 13.0 Bootcamp, where we'll dive into Advanced Number Theory—one of the most important topics in Competitive Programming.

In this session, we'll cover the Extended Euclidean Algorithm (EEA), Euler's Totient Function, Linear Diophantine Equations, Lucas Theorem, Chinese Remainder Theorem (CRT), and the Inclusion-Exclusion Principle. These powerful concepts are widely used in modular arithmetic, combinatorics, and advanced CP problems.

Date: 11th July, 2026

Time: 4:00 PM

Happy Coding!
