make 2-dimensional array a bit of life and bringing them from the abstract to the concrete realms. Please write a few lines of code defining a 2-dimensional array and how it could be used in a given application to solve a specific problem. Note: Please make sure you explain what your code is doing and what problem the 2-dimensional array solves.
Is it possible to substitute a 2-dimensional array with a 1-dimensional array?
How would this substitution work? How does the single index replace the two indexes used in a 2-dimensional array?
