.vs/ directory, matrix_multiplication_addition file and binary tree directory (TheAlgorithms#894)

* Added print function into matrix_multiplication_addition.py and removed blank space in data_structures/binary tree directory

* Removed .vs/ folder per TheAlgorithms#893

* Rename matrix_multiplication_addition.py to matrix_operation.py
