在中序遍历中,a的索引是4,则in[0:4]是二叉树的左子树的中序遍历的结果,in[5:]是二叉树的右子树的中序遍历的结果。那么pre[1:5]是二叉树的左子树的前序遍历的结果,pre[5:]是二叉树的右子树的前序遍历的结果。pre[1:5]和in[0:4]作为输入,则可以返回左子树,pre[5:]和in[5:]作为输入,则可以返回...
我们知道,二叉树的类型被我们定义为BinTree,而它的原类型是指向二叉树结点TNode的指针。我一开始犯的错误是,我认为直接传入这里的指针BinTree给函数CreateBinaryTree()就可以得到创建的二叉树。事实上这里需要传入指针的指针,即这个结构体指针的地址*BinTree。 也就是说,我们事实上传入的是** TNode,即结点指针的指...

In the code snippet above, we define a structureNodeto represent each node in the binary tree. ThecreateNode()function creates a new node with the provided data. TheinsertLevelOrder()function performs the insertion using the level order traversal approach, following the algorithm we discussed earl...
