中序遍历(Inorder Traversal)是二叉树遍历的一种方法,其遍历顺序为:先遍历左子树,然后访问根节点,最后遍历右子树。这种遍历方式被广泛应用于二叉树的各类算法中,特别是当需要按照某种特定顺序处理二叉树节点时,中序遍历往往能发挥重要作用。通过中序遍历,可以确保二叉树的每个节点都被且仅...

Preorder traversal starts printing from the root node and then goes into the left and right subtrees, respectively, while postorder traversal visits the root node in the end. #include<iostream>#include<vector>using std::cout;using std::endl;using std::string;using std::vector;structTreeNode{...

and finally nodes on the right subtree. You start traversal from root then go to the left node, then again go to the left node until you reach a leaf node. At that point in time, you print the value of the node or mark it visited and move to the right subtree. Continuing the same...
