Hacktoberfest: Update Linked List - print_reverse method (#2792) 
* chore: update print_reverse helper method

Use a generator expression instead of slicing
`elements_list` to improve the space and time complexity
of `make_linked_list` to O(1) space and O(n) time
by avoiding the creation a shallow copy of `elements_list`.

* fix: add type checking and argument typing

Add argument typing to all methods in `print_reverse`

Add doctest to helper function `make_linked_list` and
basic edge case tests to `print_reverse`

* test: add `print_reverse` test

Fix doctest syntax and remove edge case tests that are covered
by typed arguments.

Add `print_reverse` test that expects the correct values are printed
out by adding a `test_print_reverse_output` helper function.

* format code

Add algorithm for testing Project Euler solutions (#2471) 
* Add file for testing Project Euler solutions

* Remove the importlib import

* Update project_euler/solution_test.py

Co-authored-by: Christian Clauss <cclauss@me.com>

* Small tweaks to project_euler/solution_test.py

* Test Project Euler solutions through Travis

* Improved testing for Project Euler solutions:

- Renamed file so that it isn't picked up by pytest
- Fail fast on validating solutions through Travis CI

* Update validate_solutions.py

* Use namedtuple for input parameters and answer

- Remove logging
- Remove unnecessary checks for PROJECT_EULER_PATH as Travis CI
  picks up the same path

* Fix flake8 errors: line too long

* Small tweaks to validate_solutions.py

* Add all answers & back to using dictionary

* Using pytest for testing Project Euler solutions

- As we want to fail fast on testing solutions, we need to test using
  this script first before we use tests written by the author.
- As pytest stops testing as soon as it receives a traceback, we need to
  use pytest-subtests to tell pytest to test all the iterations for the
  function with given parameters.

* Print error messages in oneline format

* Separated answers into a separate file:

- Add custom print function to print all the error messages at the
  end of all the tests
- Let Travis skip if this failed
