WebDec 21, 2024 · In this post, a different approach using one queue is discussed. First insert the root and a null element into the queue. This null element acts as a delimiter. Next, pop from the top of the queue and add its left and right nodes to the end of the queue and then print at the top of the queue. Continue this process till the queues become empty.

WebLevel Order traversal. Level order traversal of below binary tree will be: We will use Queue for Level Order traversal.This algorithm is very similar to Breadth first search of graph. Steps for Level order traversal algorithm: Create empty queue and pust root node to it. Do the following when queue is not empty. Pop a node from queue and print it. WebInput: N = 5 K = 5->4->3->2->1 Output: 5 4 3 2 1 Explanation: The tree would look like 5 / \ 4 3 / \ 2 1 Now, the level order traversal of the above tree is 5 4 3 2 1. Your Task: The task is to complete the function convert() which takes head of linked list and root of the tree as the reference. The driver code prints the level order.

WebConstruct Binary Search Tree from Preorder Traversal - Given an array of integers preorder, which represents the preorder traversal of a BST (i.e., binary search tree), construct the tree and return its root. It is guaranteed that there is always possible to find a binary search tree with the given requirements for the given test cases. WebImplementation steps: BFS traversal using queue Step 1: We create an empty queue called treeQueue and initialize it with the root node. Step 2: We then run a loop until the treeQueue is empty. Inside the loop, we declare a variable called currNode to keep track of the current node during the traversal.
