WebBecause this is tree traversal, we must touch every node, making this O(n) where n is the number of nodes in the tree. BFS space complexity: O(n) BFS will have to store at least an entire level of the tree in the queue (sample queue implementation).

WebApr 23, 2008 · By that I mean you are moving from node to node through the tree correctly. Your problem comes from the way you are passing parameters. What you are trying to accomplish here is to create a String called "temp" in your Binary Tree class and then, as you "visit" each node, that node should append its "info" to the string.

WebThe preorder traversal given is H B A F D C E G J I. By using this, we construct the binary search tree and then perform the post-order traversal of the tree, starting with the left subtree of the root node, then visiting the right subtree and finally the root node.
