WebSep 8, 2016 · Anyway, if you want or need to stick to it, traversing the tree is not too bad: void printInorder (int index) { if (index == -1) return; printInorder (left [index]); System.out.print (keys [index] + " "); printInorder (right [index]); } Similarly for the other traversal orders. I am assuming -1 in either left or right means no decendant. WebFeb 18, 2024 · For the Binary Search Tree (BST), Inorder traversal gives the sorted array of values. Post-Order Traversal In this traversal, we will traverse the leftmost subtree first, then the rightmost subtree after the root. All the traversals will be in Post-Order. Let’s demonstrate an example: Here for root = 1, We’ll go to the left subtree first.

"WebMar 1, 2024 · With binary search trees we could use the same system to create a new node as to find one. Standard trees, like your file system, don’t follow any particular rules and force us to look at every item through a tree or subtree to find what we want. This is why running a search for a particular file can take so long. " - Binary search tree postorder traversal java
