Here is my analysis of the solution to Contest 362 Div. 1 Problem A:
- There are
edges per query.
- Each edge takes
to process. There are
added every query and O(q) queries, so we have
edges, meaning each edge is
to process.
- Finally, there are O(q) queries.
This gives us overall. However, the editorial does not have the
term and simply has
. How did they get rid of the
term in the analysis? Did I do something wrong here?
The theory of the matchstick. Theoretically, you can elaborate the complexity how much you want, but it is not necessary. That log(log(log(VMAX))) is just too small to be taken in account: log(log(log(1010000000))) ≈ 2.83.
This is only two
s, not three. Compared to the
term that it is next to inside the parentheses, it is not negligible:
However, I see now how it is the smaller term, so they ignored it.
