#4605 santinele

Se cunosc înălțimile a N vârfuri, plasate de la stânga la dreapta, în cadrul unui lanț muntos. Dacă plasăm o santinelă pe un vârf de o anumită înălțime, aceasta veghează vârful respectiv și maximum K vârfuri la stânga și maximum K vârfuri la dreapta acestuia, dar cu condiția ca înălțimile acestor vârfuri vegheate să fie mai mici sau egale cu înălțimea vârfului pe care se află santinela. Date fiind N, K și înălțimile celor N vârfuri, să se determine:

  • Numărul maxim de vârfuri consecutive, începând de la primul vârf al lanțului muntos (inclusiv acest vârf), ce pot fi vegheate cu o singură santinelă.
  • Numărul minim de santinele necesare ca toate vârfurile să fie vegheate.

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 santinele 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.
