`#4829` cartonase4

Maria inventează mereu câte ceva și îl provoacă la joacă pe fratele ei mai mic Petru. De data aceasta alege N cartonașe, pe care sunt înscrise valorile naturale distincte de la 1 la N (fiecare astfel de număr apare pe câte un singur cartonaș), le amestecă și le așează unul lângă altul într-un șir. Maria formulează lui Petru cerințe de următoarele tipuri:
1) Îți spun un număr poz și trebuie să determini cartonașul numerotat cu cea mai mare valoare r astfel încât primele r cartonașe din șir au înscrisă o valoare strict mai mică decât cea scrisă pe cartonașul numerotat cu poz. Dacă nu există niciun astfel de cartonaș, pentru r se stabilește valoarea 0.
2) Determină toate valorile p cu proprietatea că pe primele p cartonașe se află înscrise toate numerele naturale de la 1 la p.
3) Determină toate valorile p cu proprietatea că pe primele p cartonașe se află înscrise exact p-1 dintre numerele naturale de la 1 la p.

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 cartonase4 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.
