  A curated list of awesome places to learn and/or practice algorithms.

>Please do not ask me for solutions. With very rare exceptions, I will say no, even if you are an instructor. I recognize that my stance limits the utility of these materials, especially for self-learners, but I'm trying to optimize the learning experience of my own students at Illinois. The point of homework is not to solve that particular homework problem, but to practice solving a type of problem and get honest feedback on your progress. I've found that when solutions are available, my own students are much more likely to rely on them, rather than trying to figure out the problems themselves, which means they get both less practice and less honest feedback, which means they do worse on exams and in the course overall.

Interesting. I was asked multiple times for solutions to my self-pub ebooks that I relented. I didn't add them initially as I wanted readers to solve by themselves or ask for help if needed (and I did get a few mails, saw one of them asked on stackoverflow as well).

• C

  5 17,996 4.9 C

  Collection of various algorithms in mathematics, machine learning, computer science, physics, etc implemented in C for educational purposes.

  

I like the awesome-algorithms link, but some of the code linked is definitely not perfect. A few questionable things from one of the header files [0] in https://github.com/TheAlgorithms/C:

- Defines a macro with no parentheses

- Uses unsigned for length and capacity (should be size_t)

- Uses () instead of (void) for an empty parameter list

- Useless use of "extern" for function declarations

- I think that leading double underscores and structures ending with _t are reserved identifiers, but I don't really have a good source for this
