/**
* Replace `SortNode` to `TopKNode` in these cases:
* <li>`LimitNode + SortNode` change to `TopKNode`.
* <li>`LimitNode + OffsetNode + SortNode` change to `LimitNode + OffsetNode + TopKNode(topValue =
* limitValue+offsetValue)`.
* <li>`LimitNode + TransformNode + SortNode` change to `TransformNode + TopKNode`.
* <li>`LimitNode + OffsetNode + TransformNode + SortNode` change to `LimitNode + OffsetNode +
* TransformNode + TopKNode(topValue = limitValue+offsetValue)`.
