		for (int r = 0; r < grid.length; r++)
			for (int c = 0; c < grid[r].length; c++)
				grid[r][c] = 0;

	}
	
	int getGrid(int c, int r) {
		return grid[c][r];
	}

}



	draw(human, comp);
		input=IN.readLine();
		int Variable = Integer.parseInt(IN.readLine());
	}
	
	static void draw(Player P, Computer C) {

		case 1:		return '*';	//hit
		case -1:	return 'O';	//miss
		case 50:		return 'A';//Aircraft Carrier 5
		case 40:		return 'C';//Cruiser 3
		case 30:		return 'D';//Destroyer 4
