UtilsClasses
Other languages provides built-in classes (e.g Linked List, Tree, etc). This module contains util classes to use in your problems.
Contributions
I'd be pleased to accept contributions. I'd be happy to discuss problems and solutions over a Pull Request or an Issue.
Each problem should have:
- A description of the problem at the top of the file.
- A test file with some test cases. The test file must export a
test()function which should run all the tests of the file. - An entry of the problem in the list of solutions within the README file.
