Reshaping and Stacking

Reshaping and stacking NumPy arrays involve modifying the shape or size of an array or amalgamating multiple arrays into a single array. NumPy offers a variety of functions for these purposes, such as:

reshape(): Alters an array to a new shape without changing its data;
resize(): Changes an array's size to a new shape, which can lead to the addition or removal of elements;
vstack(): Vertically stacks arrays (row-wise) to form a single array;
hstack(): Horizontally stacks arrays (column-wise) to create a single array;
concatenate(): Joins arrays along a specified axis;
stack(): Layers arrays along a new axis, adding a dimension.

Task

Reshape the arr array to a new configuration.
Resize the arr array to a new dimension, possibly adding or omitting elements.
Vertically stack all the arrays to produce a unified array (in the order of creation).
Horizontally stack all the arrays to form a single array (in the order of creation).
