During the competition period, which was held between March 15th, 2022 and March 29th, 2022, I placed 248th out of 7,794 (top 3.2%) among global participants (who solved at least one challenge) as a solo player with a score of 12,000 points.
This page contains my write-ups for completed challenges that I couldn't solve in a few minutes. For example, many of the easier/straightforward challenges do not have a corresponding writeup. Additionally, write-ups were written such that they would be the most useful to my future self. Thus, easier challenge write-ups may contain relatively little information.
