* Update matrix_operation.py
1. Adding error checks for integer inputs
2. Adding error checks for matrix operations where size requirements do not match up
3. Added matrix subtraction function
4. included error check so only integer is passed into identity function
* Create test_matrix_operation.py
* Update matrix_ops and Add Test Cases
1. Included error checks in matrix operation. There were some cases where the functions would not work correctly.
2. PEP8 changes to matrix_operations.py
3. added test cases for matrix operations using pytest.
* Update pytest.ini
Add carriage return to end of file
@AnupKumarPanwar @ParthS007 @poyea Could I please get a quick review on this one because I made a mistake here that breaks the build for new pull requests.
* Added matrix exponentiation approach for finding fibonacci number.

* Tighten up main() and add comments on performance
* Added doctest and more explanation about Dijkstra execution.
* tests were not passing with python2 due to missing __init__.py file at number_theory folder
* Removed the dot at the beginning of the imported modules names because 'python3 -m doctest -v data_structures/hashing/*.py' and 'python3 -m doctest -v data_structures/stacks/*.py' were failing not finding hash_table.py and stack.py modules.
* Moved global code to main scope and added doctest for project euler problems 1 to 14.
* Added test case for negative input.
* Changed N variable to do not use end of line scape because in case there is a space after it the script will break making it much more error prone.
* Added problems description and doctests to the ones that were missing. Limited line length to 79 and executed python black over all scripts.
* Changed the way files are loaded to support pytest call.
* Added __init__.py to problems to make them modules and allow pytest execution.
* Added project_euler folder to test units execution
* Changed 'os.path.split(os.path.realpath(__file__))' to 'os.path.dirname()'
* Added Burrows-Wheeler transform algorithm.
* Added changes suggested by cclauss
* Fixes for issue 'Fix the LGTM issues #1024'.
* Added doctest for different parameter types and negative values.
* Fixed doctest issue added at last commit.
* Commented doctest that were causing slowness at Travis.
* Added comment with the reason for some doctest commented.
* pytest --ignore
* Added tests execution again.
* Had forgotten to add comment to file project_euler/problem_09/sol3.py

* Changed 'os.path.split(os.path.realpath(__file__))' to 'os.path.dirname()'
* 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
* Moved and renamed ~script.py to scripts/build_directory_md.py
Updated DIRECTORY.MD file
* Modified .travis.yml per suggestion in #1013
* Fixed typo per suggestions in #1013
Changing the boolean expression avoids the use of a continue statement.
This way the code becomes easier/faster to compute on lower level and it has a
better coding style.
* add gaussian filter algorithm and lena.jpg
* add img_convolve algorithm and sobel_filter
* add canny edge detection algorithm and modify sobel_filter
* format to avoid the backslashes
* Pytest the entire repo
* Do each directory for now...
* YAML files hate tabs
* Add more requirements
* pip install opencv-python
* Comment out FTP
* Add pandas and sklearn to requirements
* Comment out FTP, graphs, machine_learning, maths, neural_network, project_euler
* Update .travis.yml
* Comment out Data structures
* if __name__ == "__main__":
* pytest --ignore=
* pytest .
* Update .travis.yml
* pytest . --doctest-modules --ignore=${IGNORE}
* Ignore --ignore because it just hangs
* Create text file for numbers
* Create sol2.py
* Pythonic version of Problem #16 solution
* Update sol2.py
* Valid Python code for Python version 2-3
* Update sol2.py
`error = abs(f(a))` was declared on line 24 and line 32. It is unnecessary to have in both places.
I removed the second instance since it wastes resources to keep redefining the variable inside the for loop.
This fixes an [issue found by lgtm](66c4afbd0f/files/maths/newton_raphson.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
* minimax.py
minimax algorithm is used for game like tic tac toe. It traces the path and selects the optimal move.
* minimax.py
Minimax is used in decision making and game theory to find the optimal move for a player, when your opponent also plays optimally. It is widely used in games like Tic-Tac-Toe, Chess.
* Delete minimax.py
* Update minimax.py
* Minimax is a backtracking algorithm that is used in game theory to find the optimal move for a player, assuming that your opponent also plays optimally
* Fix typo
* Add all_permutations algorithm to backtracking directory
* Update backtracking and D&C algorithms in README
Update backtracking and divide_and_conquer algorithms in README
