#4830

Există N căsuțe (pătrățele), așezate în ordine, de la stânga la dreapta, numerotate de la 1 la N. În interiorul fiecărei căsuțe putem scrie câte un număr natural. Inițial, în fiecare căsuță scriem același număr 0. Executăm, în ordine, Q operații, care pot fi de trei tipuri:

  • Primul tip de operație se codifică prin 1 st dr nr și înseamnă că în fiecare căsuță cu indicii între st inclusiv și dr exclusiv ștergem numerele care existau înainte și scriem în locul lor același număr nr.
  • Al doilea tip de operație se codifică prin 2 poz și rezultatul operației este numărul aflat în căsuța cu indicele poz.
  • Al treilea tip de operație se codifică prin 3 st dr și rezultatul operației este numărul de apariții al valorii celei mai mari din căsuțele cu indicii între st inclusiv și dr exclusiv.

Determinați rezultatele tuturor operațiilor de tip 2 sau 3, în ordinea executării acestora.

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 casute 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!
