*@brief Returns a `RaggedTensor` containing the specified sequences of numbers.

*@par Inputs:
*@li starts: The starts of each range.
*@li limits: The limits of each range.
*@li deltas: The deltas of each range.

*@par Outputs:
*y:A Returns The `row_splits` for the returned `RaggedTensor`.The `flat_values` for the returned `RaggedTensor`.

*@attention Constraints: \n
*The input tensors `starts`, `limits`, and `deltas` may be scalars or vectors. \n
*The vector inputs must all have the same size.  Scalar inputs are broadcast \n
*to match the size of the vector inputs.

*@par Third-party framework compatibility
* Compatible with tensorflow RaggedRange operator.
