- comments
- inline comments should be two spaces after the line of code
- if a single comment takes over two lines, use a multiline comment
- sols should have nearly the same structure, same names, etc. to avoid confusion
- avoid global variables
- for the brace languages, always use braces & space em out like:
for (int i = 0; i < 2; i++) {
- an if-else should be like this:

bro i could passed gold lmao
i actually knew how to solve 2 problems
but anyways, here's the gold p1 editorial on request (actual problem here, i won't bother explaining it myself, just read the darn thing)
so it would be absolute cancer to try and actually calculate if each tuple
can get to a level where all cows have the same hunger level
not only that, calculating all the possible tuples themselves...
so yknow i was on the dp grind when someone posted this problem on the github issues for the usaco guide (you can test here, but prepare google translate)
so we have a buncha circles, intervals really
and we wanna remove some so that none of them intersect (they can be tangent tho)
so let's define min_remove[s][e]
as the minimum amount of circles we have to
remove given that the only circles we consider are the ones that are completely
"Domination". Look it up.
β Scout, TF2
after the dec contest, i have come to the conclusion that i suck a** at dp
so i was grinding cf and i came upon
this
problem that had the tag dp
but my solution was anything but that, so lemme just share my sol
