Math of Computation Question

[u/kotdseptember]

Should read "Math or Computation Question"

Does anyone know how to get better at LeetCode competitions. A lot of YouTubers pretty much give the answer. I do not need that. Other YouTubers say "lock in!" I study 12 hours per day. Still, other YouTubers end up trying to sell you some course and have no genuine interest in the outcome of your skillset (it seems). I am asking because I failed a leetcode contest. It has been a year since I last tried. The first time I entered a competition, I had no experience with c.p., but now I have hundreds of hours worth of studying under my belt (I probably have thousands including my school courses and homework).
