WebApr 10, 2024 · If not, travel to the right subtree. Repeat until you reach a leaf node. The right-most node is also defined in the same way with left and right exchanged. For example, boundary traversal of the following tree is “20 8 4 10 14 25 22”. This is how we write the traversal: root : 20. left- boundary nodes: 8. leaf nodes: 4 10 14 25.

If there exist multiple answers, you can return any of them.
WebOutput: Find the predecessor and successor of the key in BST and sets pre and suc as predecessor and successor, respectively Otherwise, set to NULL. Your Task: You don't need to print anything. You only need to set p.pre to the predecessor and s.succ to the successor. p and s have been passed in the function parameter. Constraints: WebJan 23, 2024 · Given preorder traversal of a binary search tree, construct the BST. For example, if the given traversal is {10, 5, 1, 7, 40, 50}, then the output should be root of following tree. 10 / \ 5 40 / \ \ 1 7 50.
