WebOct 27, 2024 · It is one of the common tree questions. The traversal of a binary tree has three types. They are discussed below. i) Inorder tree traversal: In this type, the left subtree is visited first, then the root, and lastly, the right subtree. Remember that any node may be a subtree in itself. WebTraverse the following binary tree by using in-order traversal. print the left most node of the left sub-tree i.e. 23. print the root of the left sub-tree i.e. 211. print the right child i.e. 89. print the root node of the tree i.e. 18. Then, move to the right sub-tree of the binary tree and print the left most node i.e. 10.
