`#2863` pyk

Fie k, n și y trei numere naturale. Fie X un șir format din n numere naturale: \( x_1, x_2, x_3, …, x_n \). Fie P produsul numerelor \( y, x_1, x_2, x_3, …, x_n \), adică \( P = y\times x_1\times x_2 \times x_3 \times … \times x_n \). Numărul P este o “k-putere” dacă există un număr natural z astfel încât \( P=z^k \).

Scrieți un program care să citească numerele \( k, n, x_1, x_2, x_3, …, x_n \) și care să determine:

1. cel mai mic și cel mai mare număr din șirul X ce sunt formate doar din cifre identice;
2. descompunerea în factori primi a celui mai mic număr natural y (y ≥ 2) cu proprietatea că numărul \( P = y\times x_1\times x_2 \times x_3 \times … \times x_n \) este o “k-putere”.

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 pyk 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.
