Write a function $$gauss$.$py$$ that performs Gaussian Elimination. This code accepts the inputs of the

coefficient matrix A $($nxn$)$ and the constant vector b $($nx$1),$ and the function returns the vector of the

solution x$($nx$1)$ and the forward$-$eliminated augmented matrix $($nxn$+1).$ Test your code against

test$\_$gauss.py
