100 Project Euler problems!
By draid, history, 4 months ago, In English

i've spent the last 3 months doing projecteuler, learned a lot of stuff, things such as dirichlet's hyperbola method, pell's equations, generating functions... it was a wonderful journey! i just felt like sharing this, pretty proud of myself! :3

    yeah... there is but it is considered unethical from projecteuler standards, if you can't solve a problem, move on or ask someone for help, but yeah still, looking at editorials before solving problems in general is a bad habit tbh, if you solved a problem you'll have access to a thread where people post their solution

      I understand.. but what should i do when get stuck?

      it is better to read somewhere to learn instead of finding someone every time.

        for the first 100 problems, i'd say you'll only need some reading comprehension and willing to read some math, mainly continued fractions and pell's equations, but really there is a good amount of not-so-math problems, my favorite one is 122, 114..117 are standard dynamic programming, if you actually gave a full day and still couldn't get much progress (me in 625 fr) you probably lack knowledge on modular forms or something, when i get really stuck and i really wanna solve the problem i just let an optimized bruteforce run over night (i know that's lame... but it's better than cheating!) so i can check the thread

    you can't be serious, have you ever heard of the internet? there is this thing called search engines, use them
