What is the post order traversal of following binary tree?
Post-order Traversal In this traversal method, the root node is visited last, hence the name. First we traverse the left subtree, then the right subtree and finally the root node.
How many tree node binary trees are possible if the post order traversal is XYZ?
For this specified post order I could figure out that there can be 5 binary trees possibly. X yzzz / \ / / \ \. xyyyyy / \ / \.
What is the possible number of binary trees that can be created with 3 nodes giving the sequence?
As we may notice, there are only 5 possible BSTs of 3 nodes. But, there exist more than 5 different Binary Trees of 3 nodes.
What is the maximum number of children that a binary tree node can have?
Any node in a binary tree can have a maximum of two children, known as Left Child and Right Child.

How many orders of traversal are applicable to a binary tree?
three orders
Explanation: The three orders of traversal that can be applied to a binary tree are in-order, pre-order and post order traversal.
What will be the Postorder traversal of the given binary tree Mcq?
In postorder traversal of binary tree right subtree is traversed before visiting root. Explanation: Post-order method of traversing involves – i) Traverse left subtree in post-order, ii) Traverse right subtree in post-order, iii) visit the root.
How many orders of traversal are applicable to binary tree?
Where is the maximum number in a binary search tree Mcq?
How will you find the maximum element in a binary search tree? Explanation: Since all the elements greater than a given node are towards the right, iterating through the tree to the rightmost leaf of the root will give the maximum element in a binary search tree.
