Description
Figure 1 shows the map of a castle. Write a program that calculates
1. how many rooms the castle has
2. how big the largest room is
The castle is divided into m * n (m<=50, n<=50) square modules. Each such module can have between zero and four walls.
# = Wall
| = No wall
- = No wall
Input
Your program is to read from standard input. The first line contains the number of modules in the north-south direction and the second line contains the number of modules in the east-west direction. In the following lines each module is described by a number (0 <= p <= 15). This number is the sum of: 1 (= wall to the west), 2 (= wall to the north), 4 (= wall to the east), 8 (= wall to the south). Inner walls are defined twice; a wall to the south in module (1, 1) is also indicated as a wall to the north in module (2, 1). The castle always has at least two rooms
Output
Your program is to write to standard output: First the number of rooms, then the area of the largest room (counted in modules).
