Dio luseis uparxoun, pou mporw na skeftw. An oloi oi arithmoi pou thes
einai Integers, tote declare an array of Y elements, kai initialize it to
zero. Kathe fora pou perneis enan arithmo, p.x 13, store 1 sto Y[13]. An
ksanapareis to arithmo 13, koita to Y[13], kai an einai 1, tote call random()
pali, gia na pareis ena allo arithmo.
Diaforetika, store the number itself in the array, and look for it through
a search, if you find it call random() again.
To deutero pernei perissotero xrono apo to proto, alla an oi arithmoi pou
 xreiazesai einai ligoi, tote den tha exeis kanena provlima.
Xrisimopoihse duo loops. The Outside loop should be a FOR loop from 1 to X.
The inside loop, should be WHILE loop, which terminates when you get a new
number from random().

Auta. Elpizw na bohthhsa.
Sygnwmh gia ta misa agglika kai misa ellinika, alla merikes fores einai
duskolo.
