Voice advertising
One sector in a soccer stadium has a rectangle shape with H
rows and W seats in each row. Some seats are empty and some are filled with
soccer fans. During the game, fans shout different slogans. It goes as follows:
If fan A from one seat starts shouting, then fans sitting on
his left, right, up, and down do the same. Then, the neighbors of these do the
same, and so on. A sponsor of the soccer
team would like that the fans "spontaneously" shout the slogan of his
company. They have hired Mirko to sit on a free seat
and starts shouting the slogan of the company. A sponsor aims that the number
of people who shout their slogan is as large as possible. Your duty is to help out Mirko
to pick a seat that will allow him to induce a shout of a maximum number of
fans.
