the code is by-product of your thoughts and solution, 4 months is a lot of time to learn coding, if you are 16+ and took 4 months to learn coding for the first time you are not giving you're all effort. solving and describe your self in code, this will take lot of practice. just learning coding alone is just 3 weeks is a max time.

Even though I've been using C for over a year, and I have a decent level understanding of C++, my mind still can't keep up. I believe that is partially due to your intentional (and required for anyone to be competitive) use of pre-existing code for each problem, but mostly it's due to how insanely fast you type :D

Hey, I have a couple of questions, if you don't mind. First: why the use of min/max in part 1?, I thought the text said to ignore anything outside of the +-50 region. Second, would your part 2 solution still work if some cubes have adjacent sides? I got fed up debugging my crappy cuboid-splicing implementation, and I found your video, and I subscribed milliseconds after. I'm too old and tired to even try the competitive stuff, so I guess I'll experience it second-hand.

@mohamedayoubneggaz15812 жыл бұрын
he just wanted to do: A[-50][-50][-50]. This is negative array indexing. Note that the coordinates are given from -50 to 50. The trick is to use the fact that C store arrays in contiguous spaces so it's possible to do A[-1] which will points to one address before the first element. It's easier to understand for 1d since no 2d recasting shenanigans are needed. In a 1D case, if you want to use an array for -50 to 50: bool original_addressed[101]; bool* negative_addressed = (bool*) &original_addressed[50]; In this example, negative_addressed[0] is like calling original_addressed[50], which is ok. If you do negative_addressed[-50], this will fetch 50 adresses before the head of the pointer which happens to be at: original_addressed[50-50] = original_addressed[0] It's just like considering the array to start at the middle and values are spread left and right. If you don't do so, you need to always add 50 so that -50 becomes 0 and 0 becomes 50 etc. Which might makes logic a bit more fuzzier. For 3D-case, you just need to figure out the starting address. Hope that helped.

Competitive programming is a beast of its own. Nobody codes like this in industry, at least what I've known. This guy does 2 things : knows how to solve complex problems (like at math olympiad), and codes his solutions (loops and some basic stuff) very fast. Yes, this is impressive and takes some training, but it is more of a sport , than real coding.
