Se dau n numere naturale, un n este un pătrat perfect. Să se construiască în memorie o matrice pătratică cu toate cele n numere, în spirală, în sens invers acelor de ceas astfel: pe prima coloană, începând cu linia 1, se vor trece primele elemente din şir (de sus în jos), apoi pe ultima linie, începând de la prima coloană până la ultima (de la stânga la dreapta), apoi pe ultima coloană, de la ultima linie la prima (de jos în sus), apoi pe prima linie, de la ultima coloană la prima (de la dreapta la stânga) şamd.

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 Spirala1 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.
