🏆 Telegram Contest for JavaScript Developers, Round 1: Results
After many hours of testing and deliberation, we are now ready to announce the results!
Reworking a text editor – essentially a core component of a messaging app – posed numerous challenges due to the wide range of formatting options and other entities, such as custom emoji.
None of the contestants were able to secure first place, yet we have increased the prize fund for Round 1 by more than 13% to fairly recognize the efforts of the participants.
The judges unanimously agreed to move forward with a second round – which begins immediately.
This time, only the winners of Round 1 will be eligible to participate. More details – in the post below.
And now – meet the winners!
2nd PLACE – $3,000

🥈 Posh Ram
🥈 Small Fly

The judges have completed the evaluation of all submissions.
The Main Task – reworking the text editor – proved to be quite challenging for the majority of contestants.
We’ve decided to expand the scope of this contest. Final scoring is currently underway, and we will announce the results on April 8, 2025, along with the details for Round 2.

We are attaching a breakdown of the Final Results for each submission.
1. Final Results:
Initially, for preliminary testing published on contest.com, we ran each test in a separate process. This allowed us to fully evaluate even solutions that crashed or hung on specific tests. However, this method disrupted many participants' performance optimizations and introduced substantial noise into the results.
Therefore, for the final evaluation, we executed all tests in a single process using a grader closely resembling the provided contest-grader.cpp. Consequently, solutions that crashed or hung on any test received a final score of 0.
2. Post-Contest Corrections:
After announcing preliminary results, several participants submitted bug fixes via comments on contest.com. Although we typically do not accept post-contest corrections, one corrected solution turned out to be significantly faster than any solution submitted during the contest. As an exception, we decided to evaluate all corrected submissions and include them in the final standings. To maintain fairness, these late submissions incurred a 20% penalty on the prize amounts awarded.
