Binary search tree postorder traversal java

WebApr 13, 2024 · Binary search Tree Traversal in java visits all nodes in a binary tree, starting with the root node, then the left subtree and finally the right subtree. Unlike linear data structure it is commonly used for accessing nodes in a specific order, creating a copy of the tree, or getting a sequence of nodes for reconstruction. 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.
