`#1130` Codat

Se consideră un șir de N numere naturale, notate x ₁, x ₂, x ₃,…, x _N. Definim pentru orice pereche de indici i, j, 1 ≤ i ≤ j ≤ N, distanța între elementele x _i și x _j ca fiind egală cu j – i.

Acest șir va fi codificat după următoarele reguli:

fiecare element din șir este înlocuit cu indicele celui mai apropiat element din șir (cel față de care distanța este minimă) strict mai mare decât el;
dacă pentru un element din șir există două elemente care respectă regula de mai sus, atunci el va fi înlocuit cu indicele mai mare, adică al elementului strict mai mare decât el, aflat în dreapta lui;
elementele de valoare maximă din șir vor fi înlocuite cu -1.

Scrieți un program care codifică un șir de N valori, după regulile descrise.

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 Codat 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.
