O(log N) !? Isn't it O(MlogN) ?
well,if it's really O(log N) , please tell me how :)

I got AC with 0.031 373 KB using brute force.
This is the dummest task I made. Tell them to read the
O(M log N) algorith in Introduction in algo(Coreman)
This sadly is my AC source:
var i,j,k,l,m,n:longint;
ok:boolean;
begin
readln(n,m,k);
for i:=0 to m-1 do
begin
l:=i;
for j:=1 to n-1 do
l:=(l*i) mod m;
if l mod m=k then
             begin
             write(i,' ');
             ok:=true;
             end;
end;
if not ok then write(-1);
end.
