`#3563` spider

Omul păianjen (Spiderman) sare de pe o clădire pe alta, aflată în imediata vecinătate, în nord, est, sud sau vest. Clădirile din cartierul omului păianjen au o înălţime exprimată în numere naturale şi sunt aşezate pe m rânduri, câte n pe fiecare rând. Spiderman va alege să sară pe una dintre clădirile vecine, care are înălţimea mai mică sau egală, iar diferenţa de înălţime este minimă. Dacă există mai multe clădiri vecine de aceeaşi înălţime, omul păianjen aplică ordinea preferenţială nord, est, sud, vest, dar nu sare încă o dată pe o clădire pe care a mai sărit. Scopul omului păianjen este acela de a reuşi să facă un număr maxim de sărituri succesive.
Scrieţi un program care determină numărul maxim de sărituri succesive, pe care îl poate efectua, pornind de la oricare dintre clădiri, precum şi poziţiile clădirilor care formează drumul maxim.

Cum funcționează evaluarea?

www.pbinfo.ro permite evaluarea a două tipuri de probleme:
probleme la care rezolvarea presupune scrierea unui program complet
probleme la care rezolvarea presupune scrierea unei secvențe de program - câteva instrucțiuni, o listă de declarații, una sau mai multe funcții, etc.
Problema spider face parte din prima categorie. Soluția propusă de tine va fi evaluată astfel:
Programul sursă este compilat folosind compilatorul corespunzător. Dacă în urma compilării se obțin erori sau avertismente, acestea sunt afișate în această pagină.
Dacă programul a fost compilat, executabilul obținut va fi rulat, furnizându-i-se unul sau mai multe seturi de date de intrare, în concordanță cu restricțiile specifice problemei. Pentru fiecare set de date se obține un anumit punctaj, în raport cu corectitudinea soluției tale.
Suma punctajelor acordate pe testele utilizate pentru verificare este 100. Astfel, soluția ta poate obține cel mult 100 de puncte, caz în care se poate considera corectă.
