// Write {0, 1, 2, 3} as tensorflow::Example inputs.
  Tensor input(tensorflow::DT_STRING, TensorShape({4}));
  for (int64_t i = 0; i < input.NumElements(); ++i) {
    tensorflow::Example example;
    auto* feature_map = example.mutable_features()->mutable_feature();
    (*feature_map)["x"].mutable_float_list()->add_value(i);
    input.flat<tstring>()(i) = example.SerializeAsString();
  }

    *   Fixed bug in `tf.data.experimental.parse_example_dataset` when `tf.io.RaggedFeatures` would specify `value_key` but no `partitions`. Before the fix, setting `value_key` but no `partitions` would result in the feature key being replaced by the value key, e.g. `{'value_key': <RaggedTensor>}` instead of `{'key': <RaggedTensor>}`. Now the correct feature key will be used. This aligns the behavior of `tf.data.experimental.parse_example_dataset` to match the behavior of `tf.io.parse_example`....
