Updated code to include:

1. Placing ships on the grid.
2. Simulating a shot with numbered coordinates separated by a space.

Necessary revisions:

1. Display separate grid instances for player's ship placement and shot placement.
2. Display separate grid instances for computer's ship placement and shot placement.
3. If vs. computer, PRNG game engine to:
	a. simulate the computer's ship placement.
	b. simulate computer's shot instead of Volley() function.
4. Clear the screen to display only the shot placement grid and NOT the ship placement grid.
5. The winning conditions need to be coded in.
