#2167

Parcul oraşului a fost neglijat mult timp, astfel că acum toate aleile sunt distruse. Prin urmare, anul acesta Primăria şi-a propus să facă reamenajări. Parcul are forma unui pătrat cu latura de n metri și este înconjurat de un gard care are exact două porți. Proiectanții de la Primărie au realizat o hartă a parcului și au trasat pe hartă un caroiaj care împarte parcul în nxn zone pătrate cu latura de 1 metru. Astfel harta parcului are aspectul unei matrice pătratice cu n linii și n coloane. Liniile și respectiv coloanele sunt numerotate de la 1 la n. Elementele matricei corespund zonelor pătrate de latură 1 metru. O astfel de zonă poate să conțină un copac sau este liberă. Edilii orașului doresc să paveze cu un număr minim de dale pătrate cu latura de 1 metru zonele libere (fără copaci) ale parcului, astfel încât să se obțină o alee continuă de la o poartă la alta. Scrieți un program care să determine numărul minim de dale necesare pentru construirea unei alei continue de la o poartă la cealaltă.
