Example 
Let us consider a bidimensional array A with m rows and n columns, whose elements are 0 or
1, 0 representing the background (paper), 1 representing the color of the design (ink).
The design is made of several objects. By "objects" we understand a set of
elements of the same type ink (1), each element having at least a neighbor on the
directions above,below, left, right or on one of the diagonals. Any two objects are
separated by elements of the same type paper (0).
|
Determine the rectangle of
minimum area which contains a maximal object (i.e. the one whose number of elements of
type ink (1) is maximal). (15 points) |
|
Place the object found at (a)
in the areas of the array which are not occupied by other objects, so that it can be
placed in as many places as possible without destroying the other objects already placed.
