var
  x:array[1..10000] of integer;
  a:array[0..10000,0..10000] of 0..1;
  way:array[1..10000] of integer;
  q,i,j,k,n,o:integer;
  fin:boolean;
begin
  fillchar(a,sizeof(A),0);
  a[0,0]:=1;
  readln(n);
  for i:=1 to n do begin
    readln(x[i]);
    if fin=false then begin
      if x[i] mod n=0 then begin writeln(1);writeln(x[i]);halt;end;
      for j:=n - (x[i] mod n) downto 0 do if (a[j,i-1]>0)and
(fin=false) then begin
        a[j+x[i] mod n,i]:=1;
        a[j,i]:=1;
        if (j+x[i] mod n) mod n=0 then begin o:=i;fin:=true;end;
      end;
    end;
  end;
  j:=0;q:=n;
  while q<>0 do
    if a[q,o]=a[q,o-1] then dec(o) else begin
      inc(j);
      way[j]:=x[o];
      q:=(q+n-x[o]) mod n;
    end;
  k:=0;
  for i:=1 to j do if way[i]=0 then inc(k);
  writeln(j-k);
  for i:=j downto 1 do
    if way[i]<>0 then writeln(way[i]);
end.
Array [0..10000,0..10000] is much greater than 1000K! (-)
