{$mode objfpc}
type
  TInputLine = packed record
    FCountryCode: array [1..3] of Char;
    FStationCode: array [1..7] of Char;
    FYear: array [1..4] of Char;
    FPressure: array [1..12, 1..5] of Char;
    FEoln: array [1..2] of Char;
  end;

var
  v: TInputLine;
  f: file of TInputLine;
begin
  AssignFile(f, 'input.txt'); Reset(f);
  while not Eof(f) do begin
    Read(f, v);
    Writeln(v.FCountryCode, '#', v.FPressure[12]);
  end;
end.
