The pre-order traversal of a binary search tree is given by 12, 8, 6, 2, 7, 9, 10, 16, 15, 19, 17, 20. Then the post-order traversal of this tree is:
- a)2, 6, 7, 8, 9, 10, 12, 15, 16, 17, 19, 20
- b)2, 7, 6, 10, 9, 8, 15, 17, 20, 19, 16, 12
- c)7, 2, 6, 8, 9, 10, 20, 17, 19, 15, 16, 12
- d)7, 6, 2, 10, 9, 8, 15, 16, 17, 20, 19, 12
Correct answer is option 'B'. Can you explain this answer?

Most Upvoted Answer
The pre-order traversal of a binary search tree is given by 12, 8, 6, ...
Explanation:
- The first element in the pre-order traversal is the root of the binary search tree. So, the root of this tree is 12.
- Next, we look for the first element greater than the root, which is 16. All the elements to the left of 16 are in the left sub-tree and all elements to the right of 16 are in the right sub-tree.
- So, the left sub-tree has the pre-order traversal 8, 6, 2, 7, 9, 10 and the right sub-tree has the pre-order traversal 15, 19, 17, 20.
- We can now recursively apply this process to the left and right sub-trees to construct the binary search tree.
- Now, to find the post-order traversal, we need to first find the post-order traversal of the left sub-tree, then the right sub-tree and finally combine them with the root.
- Applying the same process to the left sub-tree, we get the post-order traversal 2, 7, 6, 10, 9, 8.
- Similarly, applying the same process to the right sub-tree, we get the post-order traversal 17, 20, 19, 15.
- Finally, we combine the post-order traversals of the left and right sub-trees with the root to get the overall post-order traversal as 2, 7, 6, 10, 9, 8, 15, 17, 20, 19, 16, 12.
- Therefore, the correct answer is option 'B'.
