`#914` HalfSort1

Se dă un vector cu n elemente numere întregi, n fiind număr par. Să se ordoneze crescător elementele din prima jumătate a vectorului și descrescător elementele din a doua jumătate.

Se vor defini și apela următoarele subprograme:

citire, care citește valoarea lui n și cele n elemente ale tabloului
afisare, care afișează elementele tabloului, separate prin exact un spațiu
sortare, care ordonează elementele vectorului cuprinse între doi indici transmiși ca parametru. Criteriul de ordonare (crescător/descrescător) va fi transmis ca parametru.

În programele C/C++ nu se vor folosi variabile globale.

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 HalfSort1 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.
