Can anyone give me the answer of below sibling traversal objective. It is really too difficult for me.

Sometimes it can be helpful to look at the answers to other questions asked about the same topic, particularly when you're not sure even what to ask.
It can also help to skip ahead to the next step of the course and perhaps re-visit the challenge after you have finished the stage and/or reviewed some of the previous videos.
