Hello everyone!
Alright, so I've been using obsidian to document my competitive programming journey for around 2 months and wanted to share the insights and techniques that I have acquired from some trial and error. To summarize, I believe that using obsidian can be very useful for long term memory of difficult questions or algorithmic techniques. Another disclaimer I would like to point out is that (as you may be able to tell :D) I am not a very experienced competitive programmer, and the idea of algorithms and data-structures is very new to me, so for many this may seem quite naive, but perhaps I can speak for a few newer programmers on this site! :)
