What is the time complexity of post order transversal?
In postorder traversal each node in binary tree is visited: a) 1 time if it is a leaf node. c) 2 times if the node has both left and right children. 2 times because when we have to process the right child once we have finished with processing of its left child we need to check whether the node has right child or not.
What is the time complexity of inorder traversal Mcq?
6. What is the time complexity of level order traversal? Explanation: Since you have to go through all the nodes, the complexity becomes O(n).
What is the time complexity of traversing a binary tree?
The time complexity of traversing a binary tree is O(V+E) where V is the number of vertices(nodes) and E is the number of edges. Since in a binary tree, edges are V-1, the overall time complexity can be written as O(2*V – 1) or O(V).
What is inorder traversal?
Definition: Process all nodes of a tree by recursively processing the left subtree, then processing the root, and finally the right subtree. Also known as symmetric traversal.
What is the time complexity of the in order traversal in the recursive fashion?
Discussion Forum
| Que. | What is the space complexity of the post-order traversal in the recursive fashion? (d is the tree depth and n is the number of nodes) |
|---|---|
| b. | O(nlogd) |
| c. | O(logd) |
| d. | O(d) |
| Answer:O(d) |
What is the time complexity of AVL tree?
O(log n)
Insertion and Deletion time complexity of AVL tree is O(log n) and the searching time complexity of the AVL tree is O(n) which makes it better than binary search tree and red-black tree.

What is the space complexity of the inorder traversal in the recursive fashion?
What us the time complexity of traversing a tree using a breadth first search?
BFS: Time complexity is O(|V|) , where |V| is the number of nodes. You need to traverse all nodes. Space complexity is O(|V|) as well – since at worst case you need to hold all vertices in the queue.
How do you find the inorder on a traversal?
Inorder(root)
- Traverse the left sub-tree, (recursively call inorder(root -> left).
- Visit and print the root node.
- Traverse the right sub-tree, (recursively call inorder(root -> right).
How do I get the inorder traversal from Postorder?
We start with the root node, whose value would be the last item in the postorder sequence. The idea is to find boundaries of the left and right subtree of the root node in a given inorder sequence. To find the left and right subtree edges, search for the root node index in the inorder sequence.
What is an inorder traversal?
First, an inorder traversal is an algorithm you apply to a tree data structure (usually a binary tree). This algorithm takes [math]O(n)[/math] time. I think what you are missing is the other step in your reasoning is sorting.
What is the difference between binary search tree and inorder traversal?
Inorder traversal is just a walk on the tree. It visits each node exactly once that is why the complexity is O ( n). Binary search tree maintains such a structure that the inorder traversal prints the nodes in sorted order. It is the tree that maintains such a structure. Inorder traversal just does a walk on the tree.
How to analyse the time complexity of a tree traversal?
In order to analyse the time complexity of a tree traversal you have to think in the terms of number of nodes visited. If a tree has n nodes, then each node is visited only once in inorder traversal and hence the complexity is O (n). Here, the input is in terms of number of nodes in the tree and hence the complexity.
What is the difference between order and recursive traversal?
1 In Inorder traversal, traversal starts from the leftmost node of the binary tree and ends with a rightmost node of a binary tree. 2 Recursive approach In the recursive approach, start from the root node, the first call recursively left child node until we get NULL then get the current data, and then 3 Iterative approach
