#2304
Scrieţi un program care citeşte de la tastatură, în această ordine, un număr natural n, apoi n cuvinte, separate prin Enter, urmate de un număr natural k. Numerele citite sunt din intervalul [1,20], iar fiecare cuvânt este format din cel mult 20 de caractere, numai litere mici ale alfabetului englez. Cel puţin unul dintre cuvinte are k litere.
Programul construiește în memorie, apoi afișează pe ecran, un șir care să cuprindă cuvintele citite, separate prin câte un spațiu, astfel încât toate cele care au k litere să ocupe primele poziţii, iar celelalte să se regăsească în continuarea acestora, într-o ordine oarecare.

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 Cuvinte7 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.
