Binary search tree from preorder

WebDec 1, 2024 · The preorder tree traversal algorithm gets its name from the order in which the nodes of a tree are printed. In this algorithm, we first print a node. After that, we print the left child of the node. And, at last, we print the right child of the node. This process is recursive in nature. WebConstruct a full binary tree from a preorder and postorder sequence A full binary tree is a tree in which every node has either 0 or 2 children. Write an efficient algorithm to construct a full binary tree from a given preorder and postorder sequence. For example, Input: Preorder traversal : { 1, 2, 4, 5, 3, 6, 8, 9, 7 }
