Happy 15th anniversary, Codeforces, celebrated on February 19! This milestone marks not just an anniversary, but an entire era in the world of competitive programming and contests.

For the past fifteen years, Codeforces has become an integral part of programmers' lives around the globe. The platform has not only provided unique opportunities for competition and self-improvement but has also brought millions of people together under the common banner of a love for algorithms and challenges.

Personally, I registered on Codeforces only a year and a half ago, and in that time, I’ve come to realize how vast and welcoming this community-driven platform is. From the very start, I immersed myself in the atmosphere of mutual assistance and competitiveness that prevails here. Codeforces has offered me invaluable resources for learning and practice, as well as the opportunity to connect with like-minded individuals. We have tackled many diverse problems, each of which has been a new challenge, pushing me further out of my comfort zone. This invaluable experience has helped me grow and develop, becoming the best version of myself.

A huge thank you to the entire Codeforces team for their tireless work, their passion, and their commitment to creating and maintaining this platform that continues to inspire new generations of programmers. May we look forward to many more exciting contests and years of successful competitions ahead.
