What is the inorder traversal of this BST?
The InOrder traversal is also known as left-node-right or left-root-right traversal or LNR traversal algorithm. If you remember, in BST, the value of nodes in left subtree is lower than the root and values of nodes on right subtree is higher than root.
What is the output of inorder traversal?
Inorder traversal is one of the depth first tree traversal methods. Inorder traversal of binary search tree will produce the output in acending order.
What is BST explain the operations of BST?
A Binary Search Tree (BST) is a tree in which all the nodes follow the below-mentioned properties − The value of the key of the left sub-tree is less than the value of its parent (root) node’s key. The value of the key of the right sub-tree is greater than or equal to the value of its parent (root) node’s key.
What is the high level algorithm for BST in-order traversal?
Here is the high-level algorithm for BST in-order traversal. 1. Traverse the left sub-tree (keep visit the left sub tree until you reach leaf node). 2. Visit the current node. 3. Traverse the left sub-tree. (same as #1) //pay attention to visit and traverse The In order binary tree traversal will give the output in the ascending order.
What is post order binary tree traversal?
Postorder Binary Tree Traversal The post-order binary tree traversal, we traverse the left sub tree, the right sub-tree and finally visit the root node.Here is the algorithm for the post-order BST traversal. //postorder algorithm.
What is the importance of inorder traversal?
From the Interview point of view, InOrder traversal is extremely important because it also prints nodes of a binary search tree in the sorted order but only if a given tree is a binary search tree.
How to get nodes of BST in non- increasing order?
To get nodes of BST in non-increasing order, a variation of Inorder traversal where Inorder traversal s reversed can be used. Example: Inorder traversal for the above-given figure is 4 2 5 1 3.
