La un concurs de matematică participă elevi din mai multe şcoli din diferite oraşe. Pentru a se putea deosebi între ele lucrările lor, fiecare lucrare este codificată printr-un număr natural cu 3 cifre, să zicem abc, unde a (cifra sutelor) este codul oraşului, b (cifra zecilor) este codul şcolii din oraşul a, iar c (cifra unităţilor) este codul unui elev din şcoala b din oraşul a. Exemplu: lucrarea cu codul 328 este lucrarea elevului cu codul 8 de la şcoala cu codul 2 din oraşul cu codul 3. Se cunosc: un cod (al lucrării unui elev H, prietenul nostru), numărul n de lucrări premiate şi codurile acestora.
