code: def reverse_sequence(a, seq_lengths, seq_axis=1, batch_axis=0):
      """Reverse the tensor for variable length slices.
      Input is first sliced along batch axis and then elements are reversed along seq axis.
  
      Parameters
      ----------
      a : tvm.te.Tensor
         The tensor to be reversed.
  
      seq_lengths : tvm.te.Tensor
         A 1D Tensor with length a.dims[batch_axis]
         Must be one of the following types: int32, int64
         if seq_lengths[i] > a.dims[seq_axis], it is rounded to a.dims[seq_axis]
         if seq_lengths[i] < 1, it is rounded to 1
  
      seq_axis : int, optional
         The axis along which the elements will be reversed. Default is 1.
  
      batch_axis : int, optional
         The axis along which the tensor will be sliced. Default is 0.
  
      Returns
      -------
      ret : tvm.te.Tensor
         The computed result of same shape and type as of input.
