* New solution for Euler problem 67
A faster and memory efficient solution based on the template of sol1.py.
Modified the solution to be more memory efficient while reading and generating the array
and during the solution finding.
No conditions and straightforward logic.
* added return type hint
* Update project_euler/problem_067/sol2.py
Preferring comprehensions over map

Name: Prime square remainders
Let pn be the nth prime: 2, 3, 5, 7, 11, ..., and
let r be the remainder when (pn−1)^n + (pn+1)^n is divided by pn^2.
For example, when n = 3, p3 = 5, and 43 + 63 = 280 ≡ 5 mod 25.
The least value of n for which the remainder first exceeds 10^9 is 7037.
Find the least value of n for which the remainder first exceeds 10^10.

* Fix style of the first ten solutions for Project Euler
- Unify the header docstring, and add reference URLs to wikipedia
or similar
- Fix docstrings to be properly multilined
- Add newlines where appropriate
- Add doctests where they were missing
- Remove doctests that test for the correct solution
- fix obvious spelling or grammar mistakes in comments and
exception messages
- Fix line endings to be UNIX. This makes two of the files seem
to have changed completely
- no functional changes in any of the solutions were done
(except for the spelling fixes mentioned above)
* Fix docstrings and main function as per Style Guide
* Added solution for Project Euler problem 38. Fixes: #2695
* Update docstring and 0-padding in directory name. Reference: #3256
* Renamed is_9_palindromic to is_9_pandigital.
* Changed just-in-case return value for solution() to None.
* Moved exmplanation to module-level docstring and deleted unnecessary import
