Leetcode 94 binary tree inorder traversal 思路是从根节点开始,先将根节点压入栈,然后再将其所有左子结点压入栈,然后取出栈顶节点,保存节点值,再将当前指针移到其右子节点上,若存在右子节点,则在下次循环时又可将其所有左子结点压入栈中。这样就保证了访问顺序为左-根-右。
二叉树的前序遍历的解答如下:定义:前序遍历指的是先访问根节点,然后递归遍历左子树,最后遍历右子树。具体实现步骤:递归版本:判断当前节点:如果当前节点为空,返回空数组。访问当前节点:将当前节点的值放入结果数组。递归遍历左子树:如果左子节点存在,递归调用前序遍历函数于左子节点,并将返回的...
