In Question $1,$ you created an array called my$\_$arr. Use the reshape function to create a $3$x$3$ matrix named arr$\_$reshaped.

Print out arr$\_$reshaped to see the result.

Use indexing to print out the last row of the matrix and print out the element at the center of the matrix.

Create two $1-$dimensional arrays named X and Y with the elements $[3,9,5,4]$ and $[1,8,7,6],$ respectively.

Compute the dot product of X and Y and print the result.
