What is the time complexity of level order transversal?
O(n)
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). 7.
What is level order traversal?
Trees can also be traversed in level order, where we visit every node on a level before going to a lower level. This search is referred to as level order traversal or Breadth–first search (BFS), as the search tree is broadened as much as possible on each depth before going to the next depth.
What is the complexity of each traversal type?
The complexity of each of these Depth-first traversals is O(n+m). Since the number of edges that can originate from a node is limited to 2 in the case of a Binary Tree, the maximum number of total edges in a Binary Tree is n-1, where n is the total number of nodes. The complexity then becomes O(n + n-1), which is O(n).
What is the complexity of BST?
The space complexity of a binary search tree is O ( n ) O(n) O(n) in both the average and the worst cases.

What is the time complexity of BFS?
Time Complexity of BFS = O(V+E) where V is vertices and E is edges. Time Complexity of DFS is also O(V+E) where V is vertices and E is edges.
Which data structure is used in level order traversal of tree?
We will use a Queue(FIFO) data structure to implement Level order traversal, where after visiting a Node, we simply put its left and right children to queue sequentially.
What is the time complexity of level order traversal A O 1 B o’n c/o Logn d/o Nlogn?
What is the space complexity of inorder traversal?
So I know that the space complexity of a recursive in order traversal is O(h) and not O(n) as h = tree height and n = number of nodes in the tree. We are pushing n memory addresses to the call stack, therefore, the space complexity should be O(n).
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?

| Answer:O(d) |
What is the time complexity of a binary search tree to traverse all n nodes?
Searching: For searching element 1, we have to traverse all elements (in order 3, 2, 1). Therefore, searching in binary search tree has worst case complexity of O(n). In general, time complexity is O(h) where h is height of BST.
Level order traversal is just another word for the Breadth First Traversal i.e. traverse the tree level-by-level. Contrary to Depth First Traversal, where we traverse deeper into the tree, level order traversal (or breadth first traversal or breadth first search) traverses every node in a level before going into the next level.
What is the time complexity of printlevelorder ()?
For a skewed tree, printGivenLevel () takes O (n) time where n is the number of nodes in the skewed tree. So time complexity of printLevelOrder () is O (n) + O (n-1) + O (n-2) + .. + O (1) which is O (n^2). Space Complexity: O (n) in worst case. For a skewed tree, printGivenLevel () uses O (n) space for call stack.
How do you find the space complexity of a binary tree?
If the maximum width of the binary tree is w, then space complexity = O (w). The idea is simple: the width of w depends on the structure of the given binary tree.
What are the different types of DFS traversals?
In the DFS traversal of a binary tree, we access nodes in three different orders : preorder, postorder and inorder. Now there is another traversal that can access nodes in level-by-level order.
