   @reminisce numpy behavior seems to be inconsistent . For example
   ```
   >>> data = np.random.uniform(size=(4,))
   >>> data
   array([0.6677262 , 0.29855998, 0.32659663, 0.15015646])
   >>> data[2:0:-1]
   array([0.32659663, 0.29855998])
   >>> data[2:-1:-1]
   array([], dtype=float64)
   >>>
   ```
   end = 0 returns the two element array till index 1. end = -1 instead of returning 3 element array returns empty array. Ideally it should return the three element array. Otherwise there is no way to include the 0th index with negative step.
