Answer the following questions from the diagram of a Binary Tree given below:
(a)[1.0]
Write the post-order traversal of the above tree.
(b)[1.0]
State the leaf nodes of the above tree.
(c)[1.0]
State the parent of Node D and the sibling of Node E.
Answer
Answer (a)
AIPost-order traversal (left, right, root): C, E, G, F, D, B, J, I, H, A
Answer (b)
AILeaf nodes (nodes with no children): C, E, G, J
Answer (c)
AIParent of Node D = B
Sibling of Node E = F
