code: def hermesub(c1, c2):
      """
      Subtract one Hermite series from another.
  
      Returns the difference of two Hermite series `c1` - `c2`.  The
      sequences of coefficients are from lowest order term to highest, i.e.,
      [1,2,3] represents the series ``P_0 + 2*P_1 + 3*P_2``.
  
      Parameters
      ----------
      c1, c2 : array_like
          1-D arrays of Hermite series coefficients ordered from low to
          high.
  
      Returns
      -------
      out : ndarray
          Of Hermite series coefficients representing their difference.
  
      See Also
      --------
      hermeadd, hermemulx, hermemul, hermediv, hermepow
  
      Notes
      -----
      Unlike multiplication, division, etc., the difference of two Hermite
      series is a Hermite series (without having to "reproject" the result
      onto the basis set) so subtraction, just like that of "standard"
      polynomials, is simply "component-wise."
  
      Examples
      --------
      >>> from numpy.polynomial.hermite_e import hermesub
      >>> hermesub([1, 2, 3, 4], [1, 2, 3])
      array([0., 0., 0., 4.])
