code: def ifftshift(x, axes=None):
      """
      The inverse of `fftshift`. Although identical for even-length `x`, the
      functions differ by one sample for odd-length `x`.
  
      Parameters
      ----------
      x : array_like
          Input array.
      axes : int or shape tuple, optional
          Axes over which to calculate.  Defaults to None, which shifts all axes.
  
      Returns
      -------
      y : ndarray
          The shifted array.
  
      See Also
      --------
      fftshift : Shift zero-frequency component to the center of the spectrum.
  
      Examples
      --------

      >>> freqs
