We should print "2 15 19" (maybe something else), but in
sample we have only 2 15. Why?

if 19 appears, so 32 must do the same.
In this prob, we must understand to output all the X
satisfy the rule AND X <= N, that what i think about it :)

sqroot(a,n) is less then n. Remember that the result of
modulo operations are always less than modulo!!!

So sqroot(4,17) are less than 17 and of course, are
positive integers.

"The number x is called a square root a modulo n (root
(a,n)) if
x*x = a (mod n)"
so it's free to think that X can be in any range it wants !
So must put more rules that X <= N :-)
