`#2301` secv

Se consideră două numerele naturale K și S și un șir de N numere naturale a[1], a[2],…, a[N]. O secvenţă de lungime K este un subşir format din K elemente aflate pe poziţii consecutive în şir: a[i], a[i+1],.., a[i+k-1]. Parcurgând șirul de la stânga la dreapta, începând cu primul element, se elimină prima secvență de lungime K, cu suma elementelor strict mai mare decât numărul S. În urma ștergerii șirul va avea N-K elemente: a[1], a[2],…, a[N-K]. Operația de ștergere continuă după aceleași reguli până când nu mai există secvențe care pot fi eliminate.

Să se scrie un program care citind numerele N, K, S și cele N elemente din șir rezolvă cerințele:
1) Determină numărul secvențelor care se vor elimina respectând condiția din enunț.
2) Considerând că în șirul citit nu sunt posibile eliminări de secvențe conform condiției din enunț, programul determină numărul de elemente a[i] din șir cu proprietatea următoare: ștergerea lui a[i] conduce la obținerea unui șir în care se mai poate elimina cel puțin o secvență de K elemente cu sumă strict mai mare ca S.

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 secv 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.
