Fix ruff errors ()
* 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

Update 3n_plus_1.py ()
* Update 3n_plus_1.py

1. Minor issue with ValueError message: Given integer should be positive, not greater than 1, as 1 is allowed.
2. += calls underlying list extend method which might be slower. Calling apend seems more appropriate.

* Hexagonal number sequence 

A hexagonal number sequence is a sequence of figurate numbers where the nth hexagonal number hₙ is the number of distinct dots in a pattern of dots consisting of the outlines of regular hexagons with sides up to n dots, when the hexagons are overlaid so that they share one vertex.

This program returns the hexagonal number sequence of n length.

Mistake in maths/average_mode.py fixed. ()
A serious bug was addressed with this pull request. The mode function previously
didn't return the mode of the input list. Instead, it always returned the first value.
Due to lacking tests, the bug was never caught. This pull request also adds new
functionality to the function, allowing support for more than one mode.

See  for details.

* * Mistake in average_mode.py fixed. The previous solution was to returnthe
value on the first loop iteration, which is not correct, more than that it
used to delete repeating values, so result's array and check array lost
relation between each other

* Type hint added

* redundant check_list deleted

* Suggestions resolved

* output typing changed to Any
* test cases added

* Black done

File formatted

* Unused statistics import

statistics only used in doctest, now they are imported in doctest

* Several modes support added

Several modes support added

* Comment fix

* Update maths/average_mode.py
