WebDepending on the order in which we do this, there can be three types of traversal. Inorder traversal First, visit all the nodes in the left subtree Then the root node Visit all the nodes in the right subtree inorder(root->left) … WebYou are given the pre-order traversal of the tree, which is constructed by doing: output, traverse left, traverse right. As the post-order traversal comes from a BST, you can deduce the in-order traversal (traverse left, output, traverse right) from the post-order traversal by sorting the numbers.

WebAug 19, 2024 · To print data from BST you need to do inorder traversal. In case of binary search trees (BST), Inorder traversal gives nodes in non-decreasing order. To get nodes of BST in non-increasing order, a variation of Inorder traversal where Inorder traversal s reversed can be used. Algorithm Inorder (tree) 1. Web6 hours ago · Now I want to print the sequence of the LCS using post order traversal. e.g. In bottom 6th level L is on right side of - so the sequence would be - L then it lies on right side of 4th level - hence the Sqence would be - - L . this lies on left side of Maeen hence - - L Maeen and hence adding the right side - - L Maeen - - and so on till root.
