`#4535` Cal_XI

Se dă o tablă de șah formată din n linii și m coloane, definind n*m zone, unele dintre ele fiind libere, altele conținând piese, mai precis: un cal, nebuni și pioni. Calul este codificat prin cifra 2, pionii prin 1, nebunii prin 3, iar pozițiile libere prin 0. Calul care se poate deplasa pe tablă prin salturi de forma literei L, exact ca la șah (doi pași pe o direcție și un pas pe cealaltă direcție), fără a părăsi tabla, fără a trece prin zone care conțin nebuni și fără a trece de două ori prin aceeași zonă.

Determinați în câte moduri poate lua calul toți pionii și care este numărul minim de salturi pentru acest lucru, știind că salturile calului se opresc în momentul în care ia ultimul pion.

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 Cal_XI 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.
