Subject: [PATCH 2/3] Remove separate directory for
gaussian_elimination_pivoting.py
Delete the directory linear_algebra/src/gaussian_elimination_pivoting/
and move its algorithm file, gaussian_elimination_pivoting.py, into the
parent src/ directory. The gaussian_elimination_pivoting/ directory only
exists because gaussian_elimination_pivoting.py reads an example numpy
array from matrix.txt, but this input file and IO operation is entirely
unnecessary because gaussian_elimination_pivoting.py already has the
exact same array hard-coded into a variable.
