Things I don't know
I'm just in a mood to shitpost. Don't take it too seriously.
Things that I have heard of, but don't know (imagine how many things I haven't even heard of):
- The difference between
\mathcal O and\Theta for expressing time complexity. - Cosmic rays which can affect the result of radix sort.
- Homework which doesn't need to be completed by everyone.
- Car numbers with
I-s andO-s. - The time complexity of
for (j = 0; j < n; j*=2). string s; s[s.length()];without getting runtime error.- How (and why) to calculate
x\bmod -k\ (k\in\mathbb{N}^*) . - What
\mathcal O(\lfloor\log_k|n|\rfloor+1) means. - Depth-first search on a directed cyclic graph to calculate the minimum path.
- Anything on the test paper of SCP-S1.
- How
\text{\color{#808080}ProblemSetter} 's mind works.
If you know at least 3 of these things and you are not red — you are doing it wrong. Stop learning useless algorithms, go and solve some problems, learn how to use binary search.
