DouaDrumuri
#4564

Se dă o matrice de mărime N pe N care conține litere ale alfabetului englez. Definim un drum dreapta-jos ca fiind un șir de celule ale matricei care începe cu celula (1, 1), se termină cu celula (N, N), iar pentru fiecare celulă (x, y) din drum (exceptând ultima), succesoarea sa este fie (x+1, y), fie (x, y+1). Spunem că șirul de caractere generat de un drum în matrice este șirul obținut prin concatenarea valorilor celulelor drumului în ordine.

Să se găsească 2 drumuri dreapta-jos care nu se intersectează (decât în celulele (1, 1) și (N, N)) pentru care coeficientul de similaritate este maxim. Coeficientul de similaritate a 2 drumuri reprezintă numărul de poziții i pentru care a[i] = b[i], 0 ≤ i < lungime(a), lungime(b), unde a și b sunt șirurile generate de cele 2 drumuri.

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 DouaDrumuri 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!
