`#700` Labir

Şoricelul Jerry este (pentru a câta oară ?) în labirint. Labirintul poate fi codificat ca o matrice cu n linii şi m coloane formată din n*m celule pătratice identice. Liniile se numerotează de la 1 la n, iar coloanele de la 1 la m. Labirintul este format din celule libere şi din celule ocupate de pereţii labirintului.
La momentul iniţial, Jerry se găseşte într-o anumită celulă liberă şi misiunea lui este să ajungă la destinaţie într-o altă celulă liberă precizată. Șoricelul se poate deplasa din celula curentă în oricare dintre cele patru celule cu care aceasta are în comun o latură şi nu poate ieşi în afara labirintului. Este posibil ca el să nu poată să ajungă de la poziţia iniţială la cea finală trecând doar prin celule libere. În această situație el este nevoit să sfărâme peretele în anumite celule. Jerry şi-a pregătit dinamită în acest scop, pentru că nu i se pare optim să roadă peretele cu dinţii.
Cunoscând dimensiunile n şi m ale labirintului, coordonatele celulei de plecare şi ale celulei destinaţie, precum şi coordonatele celulelor ocupate de pereţi, să se determine numărul minim de celule ocupate, pe care Jerry trebuie să le dinamiteze pentru a putea să ajungă la destinaţie.

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 Labir 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.
