* fix: Syntax Error lgtm display in matrix/matrix_operation.py.
* Testing for None should use the 'is' operator.
* fix: Too many arguments for string format.
* fix: supress lgtm alert as false positive.
* style: Unnecessary 'pass' statement.
* Revert "fix: Syntax Error lgtm display in matrix/matrix_operation.py."
This reverts commit 4c629b4ce1.
* Add Kth lexicographic permutation
Function that computes the kth lexicographic permtation of 0,1,2,...,n-1 in O(n^2) time
* Update kth_lexicographic_permutation.py
Addressed requested changes
* Added OOP aproach to matrices
* created methods for minors, cofactors, and determinants and added corresponding doctests
* Added methods for adjugate, inverse, and identity (along with corresponding doctests) to matrix_class.py
A small bug persists that causes the doctest to fail.
After a couple Matrix objects are printed, the next one is printed in a different format.
* formatted matrix_class.py with python/black
* implemented negation and exponentiation as well as corresponding doctests in matrix_class.py. Also implemented eq and ne comparison operations
* changed __str__ method in matrix_class.py to align with numpy standard and fixed bug in cofactors method
* removed property decorators from several methods in matrix_class.py
* Add radix2 FFT
Created a dynamic implementation of the radix - 2 Fast Fourier Transform for fast polynomial multiplication.
Reference: https://en.wikipedia.org/wiki/Cooley%E2%80%93Tukey_FFT_algorithm#The_radix-2_DIT_case
* Rename radix2_FFT.py to radix2_fft.py
* Update radix2_fft printing
Improved the printing method with f.prefix and String.join()
* __str__ method update
* Turned the tests into doctests
* Binomial Heap
Implementation of Binomial Heap. Reference: Advanced Data Structures, Peter Brass
* Update binomial_heap.py
* Update binomial_heap.py
* Update binomial_heap.py
- Fuller documentation of binomial heap
- Update unit tests
- Replace printing method by overwriting __str__()
* Update binomial_heap.py
- Added more tests
- Added to the documentation
- Stylistic editing
- mergeHeaps now also returns a reference to the merged heap
- added a preOrder function that returns a list with the preorder of the heap
* Update binomial_heap.py
Changed the unit tests structure
* Turned the tests into doctests
* Created Sherman Morrison
* Added docstring for class
* Updated Sherman morrison
1. Added docstring tests
2. Tweaked __str__() using join
3. Added __repr__()
4. Changed index validation to be independent method
* Applied cclauss's point
1. Reduced line length for __str__()
2. Removed parens for assert
* svm.py

I would like to add the Support Vector Machine algorithm implemented in Python 3.6.7
Requirements:
- sklearn
* update svm.py
* update svm.py
* Update and renamed to sorted_vector_machines.py
* Updated sorted_vector_machines.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
* Fixing lgtm issue in basic_graphs per ##1024
* Fixed lgtm issue per @cclauss recommendation in #1024
