Binary tree without recursion
WebFor traversing a (non-empty) binary tree in a postorder fashion, we must do these three things for every node nstarting from the tree’s root: (L)Recursively traverse its left subtree. When this step is finished, we are back at nagain. (R)Recursively traverse its right subtree. When this step is finished, we are back at nagain. (N)Process nitself. WebGiven a binary tree, return true if a node with the target data is found in the tree. Recurs down the tree, chooses the left or right branch by comparing the target to each node. static int lookup(struct node* node, int target) { // …
