+completed: makeChange, fizzBuzz, isPalindrome, Factorial out of 10 function in ALGORITHMS.md for CLassic, Numeric, and Set (not done)
+
+ - [X] Artifact produced is a fork of the core-algorithms repo.
+ - [X] Can run all tests with npm test.
+ - [X] All tests are passing.
+ - [X] For each algorithm in the algorithms list, there exists:
+ - [X] a test file with at least 2 unit tests using valid inputs, and at least 1 unit test using invalid inputs.
+      an implementation file with a correct implementation of the algorithm.
+ - [X] Repository includes a README file with basic installation and setup instructions.
+ - [X] All dependencies are properly declared in package.json.
+ - [X] All major features are added via pull requests with a clear description and concise commit messages.
+ - [ ] Code uses a linter and there are no linting errors.
+ - [X] Variables, functions, files, etc. have appropriate and meaningful names.
+ - [X] Functions are small and serve a single purpose.
+ - [X] The artifact produced is properly licensed, preferably with the MIT license.
