`#1946` Zece

Pentru cei elevi din clasa a VI-a competiția este foarte importantă și, pentru a se pregăti suplimentar, aceștia lucrează de pe site-ul www.PROBLEMEINFORMATICA.RO.
Pentru a-i încuraja, profesoara de informatică le promite câte o notă de 10 primilor k elevi, cei mai harnici și sârguincioși.
Dacă observă că mai sunt elevi care au același număr de probleme rezolvate ca și cel de pe poziția k, atunci profesoara, echidistantă, mai pune în plus note de 10 la toți aceștia.
Să se scrie un program care, citind numărul N de elevi ai clasei, numărul k de elevi notați cu 10 și N valori reprezentând numărul de probleme rezolvate de fiecare elev, rezolvă cerințele:
1. Afișează în ordine descrescătoare numărul de probleme lucrate de elevii care vor primi nota 10.
2. Afișează în ordinea descrescătoare a numărului de probleme rezolvate, numerele de ordine ale tuturor elevilor care primesc nota 10.

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 Zece 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.
