#238 Zone

Se dă un număr natural n şi un tablou unidimensional cu 3*n elemente, numere naturale cu cel mult 4 cifre. Tabloul este împărţit în trei zone, cu câte n elemente: prima zonă conţine primele n elemente din tablou, a doua zonă conţine următoarele n elemente din tablou, restul elementelor fiind în zona a treia.

Se cere interschimbarea primulul element par (dacă există) al zonei unu cu ultimul element impar (dacă există) al zonei trei. În cazul în care unul dintre elementele care urmează a fi interschimbate nu există, tabloul rămâne nemodificat.

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 Zone 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.
