#883 Traversare

Se consideră harta unei suprafețe deșertice, dată sub forma unei matrice cu n linii și m coloane, formată din n*m zone. Fiecare zonă poate fi accesibilă sau inaccesibilă. Dintr-o zonă accesibilă se poate trece în altă zonă accesibilă învecinată cu prima pe linie sau pe coloană.

Un călător dorește să traverseze deșertul de la nord (prima linie) la sud(ultima linie). Pentru aceasta el poate sa aleagă oricare zonă accesibilă de pe prima line și dorește să ajungă pe ultima linie cu număr minim de pași.

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 Traversare 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.
