`#2448` patrate3

Un elev a desenat un set format din mai multe pătrate care conțin numere naturale nenule, distincte, consecutive, dispuse în număr egal pe laturi. Pe latura fiecărui pătrat sunt scrise un număr impar de valori. În fiecare pătrat, numerele sunt scrise în ordine crescătoare parcurgând laturile sale, începând din colțul stânga-jos, în sensul invers al acelor de ceasornic. Elevul a numerotat pătratele cu 1, 2, 3 etc., în ordinea strict crescătoare a numărului de valori conținute de fiecare. Diferența dintre cel mai mic număr din pătratul P (1 < P) și cel mai mare număr din pătratul P - 1 este egală cu 1.
Scrieţi un program care rezolvă următoarele două cerinţe:
1. citește un număr natural M și determină numărul K de valori conținute de pătratul numerotat cu M;
2. citește un număr natural N și determină numărul T al pătratului care conține numărul N pe una dintre laturi.

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 patrate3 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.
