Compar

#1055
Ana şi Bogdan au inventat jocul “Compar”. Ana scrie pe tablă o secvenţă formată din N numere naturale distincte cuprinse între 1 şi N, apoi compară fiecare două numere învecinate din secvenţă scriind între ele semnul < sau semnul >, după caz.
De exemplu, dacă secvenţa de pe tablă este 6 4 2 1 3 5, după compararea elementelor învecinate şi inserarea semnelor în secvenţă, Ana obţine:
6>4>2>1<3<5
După aceea Ana şterge cele N elemente ale secvenţei şi păstrează numai semnele, astfel:
>>><<
La final, Ana îi arată lui Bogdan şirul semnelor şi îi cere să reconstituie secvenţa de numere naturale scrisă iniţial pe tablă.
Cunoscând şirul semnelor construit de Ana, scrieţi un program care să îl ajute pe Bogdan să reconstituie secvenţa de numere naturale distincte scrisă iniţial pe tablă.

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 Compar 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.
Du-te sus!
