#864

Se dă o matrice cu n linii și m coloane și elemente 0 sau 1, reprezentând planul unui teren în care 0 reprezintă o zonă accesibilă, iar 1 reprezintă o zonă inaccesibilă. O zonă a terenului are ca și coordonate linia și coloana corespunzătoare din matrice. Într-o zonă cunoscută a matricei se află un robot, iar în altă zonă, e asemenea cunoscută, se află o roboțică. Determinați numărul minim de pași prin care robotul va ajunge la roboțică. Dacă nu este posibil ca robotul să ajungă la roboțică, rezultatul va fi -1.

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 Roboti 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.

Du-te sus!
