In this article, we will learn about the non recursive algorithm of tree traversals like algorithm for pre-order, post-order and in-order. Submitted by Prerana Jain, on July 26, 2018 1) Algorithm for PostorderIn this traversal first, traverse the leftmost subtree at the external node then ...
The title string itself is a text node and a leaf. When we are doing a preorder traversal we are visiting each node in the tree in the following order So a preorder traversal is a ordering of the elements as they are ordered in the source code. San Francisco Bay Area Professional Blog...
因为是preorder traversal, 我们需要先print root,然后左节点,最后右节点,而且root左边子树一定比右边子树先print出来,所以,我们可以先把当前root的右节点压栈,然后把root的左节点压栈,这样每次从栈里取的时候,可以保证左边节点的root先取。同时,每次取了当前节点,我们进行同样的操作(先压右节点,再压左节点),这样可...

1. 中序遍历(In-order Traversal):先访问左子树,然后是根节点,最后访问右子树。这种遍历方式可以按照“左-根-右”的顺序访问所有节点。 2. 前序遍历(Pre-order Traversal):先访问根节点,然后是左子树,最后访问右子树。这种遍历方式可以按照“根-左-右”的顺序访问所有节点。 3. 后序遍历(Post-order Traversal...
This general non-recursive algorithm can visit every nodes of a binary tree in preorder, inorder, or postorder traversal sequence. The algorithm analysis shows that this new algorithm is efficient and easy to understand. The implementation of this new algorithm was done in C and the complete ...
