* 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!

* fix: fix mypy errors
Update binary_search_tree `arr` argument to be typed as a list
within `find_kth_smallest` function
Update return type of `merge_two_binary_trees` as both inputs can
be None which means that a None type value can be returned from
this function

* Update sol1.py

* Fix: use proper path to open files
* Commit suggestions:
- Use list comprehension instead of map
- Sort imports using isort
* Changes made as suggested (simplified a lot):
- List and set comprehension instead of itemgetter
- Using enumerate as it's easy to read
- Divided into list of card values and set of card suit as set will
remove all the duplicate values. So, no need for double indexing.
- Add test for testing multiple calls to five_high_straight function
* Add suggestions and simplified:
- Split generate_random_hands function into two:
- First will generate a random hand
- Second, which will be called, will return a generator object
