#3114 abq

Fie o matrice cu n linii (numerotate de la 1 la n) și m coloane (numerotate de la 1 la m) ce conține doar literele a și b. Se definește un drum de la o poziție (xs, ys) la o alta (xf, yf) ca fiind o succesiune de pași care pornește din coordonatele (xs, ys) și ajunge în (xf, yf) și care trece numai prin componente care memorează litera a. La fiecare pas, de la o poziţie (i, j) se poate trece într-una din poziţiile (i+1, j), (i-1, j), (i, j+1), (i, j-1). Lungimea drumului este dată de numărul de componente care compun drumul.

Având la dispoziție q întrebări date sub forma a patru numere naturale xs ys xf yf, trebuie să răspundeți pentru fiecare întrebare care este lungimea minimă a unui drum de la (xs, ys) la (xf, yf) care trece numai prin componente ce memorează litera a. Dacă un astfel de drum nu există, veți afișa valoarea –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 abq 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.
