`#1332` TraseuCal

Se dă o tablă de șah formată din n linii și m coloane, definind n*m zone, unele dintre ele fiind libere, altele conținând obstacole. În zona de coordonate 1 1 se află un cal care se poate deplasa pe tablă în L, ca la șah, fără a părăsi tabla, fără a trece prin zone care conțin obstacole și fără a trece de două ori prin aceeași zonă.

Determinați o modalitate prin care calul poate ajunge în zona de coordonate n m – unde se află o căpiță de fân.

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 TraseuCal 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.
