Reshaping and stacking `numPy` arrays refers to changing the shape or size of an array or combining multiple arrays into a single array. `NumPy` provides several functions for reshaping and stacking arrays, such as:
- ```reshape()```: Reshapes an array to a new shape;
- ```resize()```: Resizes an array to a new shape, potentially adding or removing elements;
- ```vstack()```: Stacks arrays vertically (row-wise) to create a single array;
- ```hstack()```: Stacks arrays horizontally (column-wise) to create a single array;
- ```concatenate()```: Concatenates arrays along a given axis;
- ```stack()```: Stacks arrays along a new axis.

In this project, we are going to understand what Numpy is and why it is so powerful.
