banana
Se consideră o pădure tropicală, reprezentată sub forma unui caroiaj dreptunghiular. Celula din colţul stânga sus al caroiajului are coordonatele (1, 1)
, iar coordonatele celorlalte celule sunt determinate de linia şi coloana pe care se află. În anumite celule ale caroiajului sunt plasaţi bananieri; o celulă conţine cel mult un bananier. Mai mulţi bananieri care se învecinează pe orizontală sau verticală formează o zonă de bananieri. Într-o astfel de zonă, CEKILI se deplasează uşor, cu agilitatea-i cunoscută, de la un bananier la altul. Determinaţi numărul maxim de bananieri care se poate obţine prin conectarea a exact K
zone.
