* scoring_algorithm: Moves doctest into function docstring so it will be run
* [mypy] annotates other/scoring_algorithm
* [mypy] renames temp var to unique value to work around mypy issue in other/scoring_algorithm
reusing loop variables with the same name and different types gives
this very confusing mypy error response.
pyright correctly infers the types without issue.

* 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.

* Fix validate_initial_digits of credit_card_validator.py
@Bhargavishnu I think that I broke the logic of validate_initial_digits which should require that credit_card_number[0] is 3 before checking that credit_card_number[1] is 4, 5, or 7. Please verify the new changes and the new test cases to make sure that this is correct. Thanks!
