      Check whether the provided array or dtype is of the string dtype.
  
      If an array is passed with an object dtype, the elements must be
      inferred as strings.
  
      Parameters
      ----------
      arr_or_dtype : array-like or dtype
          The array or dtype to check.
  
      Returns
      -------
      boolean
          Whether or not the array or dtype is of the string dtype.
  
      Examples
      --------
      >>> is_string_dtype(str)
      True
      >>> is_string_dtype(object)
      True
      >>> is_string_dtype(int)
