WebJul 21, 2024 · Construct Full Binary Tree from given preorder and postorder traversals. Given two arrays that represent preorder and postorder traversals of a full binary tree, construct the binary tree. Full Binary Tree is a binary tree where every node has either 0 or 2 children. Illustration: Following are examples of Full Trees. WebThe idea is to build the complete binary tree level-by-level. Following is a pseudocode for a simple queue -based algorithm using level order traversal: construct (head): root —> next_node (head) q —> empty queue q.enqueue (root) while (next_node (head)) node —> q.dequeue () node.left = next_node (head) q.enqueue (node.left)
