1) Preorder traversal Totraverse a binary tree in preorder, following operations are carried out: Visit the root. Traverse the left sub tree of root. Traverse the right sub tree of root. Note:Preorder traversal is also known as NLR traversal. ...
If we are given a binary tree and we need to perform a vertical order traversal, that means we will be processing the nodes of the binary tree from left to right. Suppose we have a tree such as the one given below. If we traverse the tree in vertical order and print the nodes then...

从大的层面讲,Binary Tree 可以用DFS和BFS。 对于BFS,我们需要iterative with queue。 对于DFS,Binary Tree 有三种traversal的方式: ** Inorder Traversal: left -> root -> right ** Preoder Traversal: root -> left -> right ** Postoder Traveral: left -> right -> root ...
