==Cerința== Gigel vrea un calculator nou care are prețul <span style=“color: red”> x</span>. Tatăl acestuia, fiind profesor de matematica, i-a spus ca îi va cumpăra calculatorul dacă prețul <span style=“color: red”> x</span> al acestuia este norocos. Un număr <span style=“color: red”> x</span> este norocos dacă pătratul acestuia se poate scrie ca sumă de <span style=“color: red”> x</span> numere consecutive. De exemplu, <span style=“color: red”> x = 7</span> este număr norocos deoarece, <span style=“color: red”> 7 * 7 = 4 + 5 + 6 + 7 + 8 + 9 + 10</span>. Gigel a obţinut <span style=“color: red”> T</span> oferte de preț și dorește să știe pentru fiecare dintre acestea dacă prețul este corespunzătar restricției pe care i-a impus-o tatăl său.
