code: def erf_zeros(nt):
      """Compute the first nt zero in the first quadrant, ordered by absolute value.
  
      Zeros in the other quadrants can be obtained by using the symmetries erf(-z) = erf(z) and
      erf(conj(z)) = conj(erf(z)).
  
  
      Parameters
      ----------
      nt : int
          The number of zeros to compute
  
      Returns
      -------
      The locations of the zeros of erf : ndarray (complex)
          Complex values at which zeros of erf(z)
  
      Examples
      --------
      >>> from scipy import special
      >>> special.erf_zeros(1)
      array([1.45061616+1.880943j])
  
      Check that erf is (close to) zero for the value returned by erf_zeros
  
      >>> special.erf(special.erf_zeros(1))
      array([4.95159469e-14-1.16407394e-16j])
