Input

Program requires an Input file and an Output file.

Input File

Input file should be of the following format

1. GridSize (0<M<10)
2. Number of ships for each player
3. Player 1 ship positions, should be of format x1,y1:x2,y2:x3,y3:x4,y4
4. Player 2 ship positions, should be of format x1,y1:x2,y2:x3,y3:x4,y4
5. Total number of missiles for each player (0<T<100)
6. Player 1 Moves, should be of format x1,y1:x2,y2:x3,y3:x4,y4
7. Player 2 Moves, should be of format x1,y1:x2,y2:x3,y3:x4,y4

Since it was not specifically mentioned in the problem as to how the coordinate system of the
board works. Hence, we are assuming that (0,0) lies in the top left corner and (m,m) in bottom right.
Final depiction of the board looks as follows

     (0,0) (0,1) (0,2)
(1,0)  _     _     _
(2,0)  _     _     _

Output file

Program requires an output file to write the result back to the file.
If file does not exist, one will be created.
If file exists, then the data is overwritten

Output

Programs sample output in the Output File will look as follows.

Player1
O O _ _ _
_ B O _ _
B _ _ X _
_ _ _ _ B
_ _ _ X _

Player2
_ X _ _ _
_ _ _ _ _
_ _ _ X _
B O _ _ B
_ X _ O _

P1: 3
P2: 2
Player1 wins

• O - represents a missed hit by the opponent
