`#2844` Circular List Insert

Se consideră o listă circulară simplu înlănțuită, alocată dinamic, cu n elemente, numere naturale citite de la tastatură; primul element al acestei liste este considerat element curent. Se citesc m numere naturale și pentru fiecare se aplică următoarea operație:

pentru numărul citit x elementul curent al listei avansează cu x poziții;
după elementul curent actual se inserează dublul său și elementul inserat devine element curent.

Să se afișeze elementele listei după cele m operații. Afișarea începe cu elementul care a fost element curent imediat după citire.

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 Circular List Insert 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.
