`#1341` Protest

În țara lui Zoli trăiesc n persoane, numerotate de la 1 la n, iar Zoli are numărul de ordine 1. Zoli s-a săturat de sistemul politic, așa că s-a decis să iasă în stradă. Deoarece Zoli este o persoană sociabilă, are prieteni din diverse cercuri pe care s-a gândit să îi cheme cu el. Zoli își va anunța prietenii, care la rândul lor își vor anunța prietenii și așa mai departe.
Știm însă că unele persoane sunt scandalagii, iar Zoli este un om pașnic și preferă să nu trimită invitația acestora.
Zoli vă cere să îi spuneți numărul de persoane cu care se va întâlni la protest.

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 Protest 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.
