+ As per usage examples, clause literals are a list of strings.
+ Note: symbols extracted from literals are expected to be exactly two characters.
+ self.literal boolean values are initialized to None, so must be optional
+ model values should be Booleans, but aren't guaranteed to be non-None
in the code.
+ uses newer '... | None' annotation for Optional values
+ clauses are passed to the Formula initializer as both lists and sets, they
are stored as lists. Returned clauses will always be lists.
+ use explicit tuple annotation from __future__ rather than using (..., ...)
in return signatures
+ mapping returned by dpll_algorithm is optional per the documentation.

* 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.

* The default value for **seed** is the result of a function call
The default value for **seed** is the result of a function call which is not normally recommended and causes flake8-bugbear to raise a B008 error. However, in this case, it is accptable because `LinearCongruentialGenerator.__init__()` will only be called once per instance and it ensures that each instance will generate a unique sequence of numbers.
* The default value for **backend** is the result of a function call
The default value for **backend** is the result of a function call which is not normally recommended and causes flake8-bugbear to raise a B008 error. However, in this case, it is accptable because `Aer.get_backend()` is called when the function is definition and that same backend is then reused for function calls.

* Create medianOf TwoArrays.py
This code finds the median of two arrays (which may or may not be sorted initially).
Example:
Enter elements of an array: 1 5 4 2
Enter elements of another array: 1 7 4 2 7
The median of two arrays is : 4

Diffie Hellman algorithm to generate a secret key.
* Update sdes.py
* Format code with psf/black and add doctests
* Create autocomplete_using_trie.py
The program aims to design a trie implementation for autocomplete which is easy to understand and ready to run.
* Removed unused import

* Run the code through Black and add doctest
Both of the two files implemented sieve of eratosthenes.
However, there was a bug in other/finding_primes.py, and the time complexity was larger than the other.
Therefore, remove other/finding_primes.py and add doctest tomaths/sieve_of_eratosthenes.py.
* Added print function into matrix_multiplication_addition.py and removed blank space in data_structures/binary tree directory
* Removed .vs/ folder per #893
* Rename matrix_multiplication_addition.py to matrix_operation.py
* Added main() function and simplified password generation.
* Modified password_generator.py file according to suggestions in #968
Since `j` is redefined before it is used, it makes more sense to declare it with the value `None` instead of `1`.
This fixes a [warning from lgtm](66c4afbd0f/files/other/primelib.py)
The Fisher–Yates shuffle is an algorithm for generating a random permutation of a finite sequence.
