https://mybinder.org/ Should I make a binder ? :) Or if there is a binder link, it's well hidden.

Is there a reason why in travis CI config the command black --check . || true is run? I don't see the point in checking if files needs to be reformatted if it's just going to be ignored anyways.

Currently running black --line-length 127 --check . -> 399 files would be reformatted, 74 files would be left unchanged.

然后可以在 htc 里 link 一下。（我刚开始写 Wiki 的时候就不知道怎么做到“一个 pr 只干一件事”）

Some possible suggestions are - sites which teach algorithms, sites which interactively visualize different algorithms. Also, notebooks/question pages of ACM themed contests can be added.

We need to improve the comments explaining the main ideas / insights of the solution

The code from https://cp-algorithms.com/graph/push-relabel.html doesn't work.
Very easy to see that it is buggy, since the code doesn't use the target vertex t at all.

• should take a functor, not a function pointer (done in #74)
• should only return once b - a is smaller than 1/k times the original interval size

...the same way we do during self-testing after #545.

Do you think a more detailed README file describing each source code file in the "code" folder might be made available in the future?

The current test suite in webapp/tests/ is a start but not very satisfactory.

Some ways to improve:

• Remove duplication between the tests and clean them up
• Create a good clean template to test e.g. jury interface functionality that can easily be populated for the various data types;
• Add tests using said template;
• Add tests for the API

I have written two pages in Japanese.

These documents should be translated to English.

Hi friends, since many of you are starting to contribute for Hacktoberfest.

To not disallow beginners to contribute to the project, this issue can be taken up by anyone starting to learn data structures and algorithms.

You need to start solving the problems in the Hackerrank's Tracks and add your solutions in the branch named trackname in a new f

Is your feature request related to a problem? Please describe.

More flexible head comments (like adding current time and so on).
