Hello @ankit152,

So, you didn’t try to understand the code.
You just copied it.:sweat_smile:

Let’s understand the code first:

What are we doing?
you have to consider 4 cases:
2 => 1 <= END
3 => 2 <= END
END => 3 <= END
case 1:
if root->left!=null &&root>right!=null
2 => 1 <= 4
then you have to print values on the both sides and in mid there will be root->data
case 2:
if root->left==null and root->right==null
END => 3 <= END
case 3:
if root->left!=null and root->right==null
2 => 1 <= END
case 4:
if root->left==null and root->right!=null
END => 3 <= 7
Note in mid parent root node will be there.

I think now you can correct the code yourself.
In case you still face any issue, feel free to ask.

Hope, this would help.
Give a like if you are satisfied.
