$3.$ Write a python program that creates the following $1$D NumPy arrays.

a $=[1,2,3]$

b $=[4,5,6]$

c $=[7,8,9]$

Then create matrices $(2$D arrays$)$ such that:

$$ The new matrix A is constructed by stacking a$,$ b$,$ and c vertically.

$$ The new matrix B is constructed by stacking a$,$ b$,$ and c horizontally.

$$ Construct a new matrix C such that matric C will be the transpose of matrix A$.$

$$ Construct a new matrix B such that matric D will be the transpose of matrix B$.$

Finally, print the arrays.
