Fix ruff errors (#8936)
* Fix ruff errors

Renamed neural_network/input_data.py to neural_network/input_data.py_tf
because it should be left out of the directory for the following
reasons:

1. Its sole purpose is to be used by neural_network/gan.py_tf, which is
   itself left out of the directory because of issues with TensorFlow.

2. It was taken directly from TensorFlow's codebase and is actually
   already deprecated. If/when neural_network/gan.py_tf is eventually
   re-added back to the directory, its implementation should be changed
   to not use neural_network/input_data.py anyway.

* updating DIRECTORY.md

* Change input_data.py_tf file extension

Change input_data.py_tf file extension because algorithms-keeper bot is being picky about it

Fix radix_tree.py insertion fail in ["*X", "*XX"] cases (#8870)
* Fix insertion fail in ["*X", "*XX"] cases

Consider a word, and a copy of that word, but with the last letter repeating twice. (e.g., ["ABC", "ABCC"])
When adding the second word's last letter, it only compares the previous word's prefix—the last letter of the word already in the Radix Tree: 'C'—and the letter to be added—the last letter of the word we're currently adding: 'C'. So it wrongly passes the "Case 1" check, marks the current node as a leaf node when it already was, then returns when there's still one more letter to add.
The issue arises because `prefix` includes the letter of the node itself. (e.g., `nodes: {'C' : RadixNode()}, is_leaf: True, prefix: 'C'`) It can be easily fixed by simply adding the `is_leaf` check, asking if there are more letters to be added.

- Test Case: `"A AA AAA AAAA"`
  - Fixed correct output:
  ```
  Words: ['A', 'AA', 'AAA', 'AAAA']
  Tree:
  - A   (leaf)
  -- A   (leaf)
  --- A   (leaf)
  ---- A   (leaf)
  ```
  - Current incorrect output:
  ```
  Words: ['A', 'AA', 'AAA', 'AAAA']
  Tree:
  - A   (leaf)
  -- AA   (leaf)
  --- A   (leaf)
  ```

*N.B.* This passed test cases for [Croatian Open Competition in Informatics 2012/2013 Contest #3 Task 5 HERKABE](https://hsin.hr/coci/archive/2012_2013/)

* Add a doctest for previous fix

* improve doctest readability

[mypy] Fix type annotations in data_structures/binary_tree (#5518)
* 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

* updating DIRECTORY.md

singly_linked_list: Added additional documentation, type hints and test cases (#4988)
This is a followup to https://github.com/TheAlgorithms/Python/pull/4973#issuecomment-933117382

As per given suggestion, I've added type hints to certain methods that don't have them.  I have also added documentation and example doctests as a usage example for (most of) those that don't have them.

I have also added another test case following the previous test case's format. I noticed that the existing test case from previous pull request might be redundant with the ones I've made, so I decided to create a specific situation where the linked list would have to keep different kinds of data types for each node, in `test_singly_linked_list_2` test function.

Some minor changes in strings has been done to keep things consistent with other parts of the document. If it is undesirable, please let me know.
