the biggest problem lies in finding the time complexity of finding the predecessor nodes of all the nodes in the binary tree. Intuitively, the complexity is O(nlogn)O(nlogn), because to find the predecessor node for a single node related to the height of the tree. But in fact, finding ...

Identify the root of the binary tree using the last element of the postorder list. Find the root's position in the inorder list to determine the left and right subtrees. Recursively construct the left and right subtrees using the respective portions of the inorder and postorder lists. Return...
Splay trees, a form of self-adjusting binary tree, were introduced by Sleator and Tarjan in the early 1980s. Their main use is to store ordered lists. The idea is to keep the trees reasonably well balanced through a 'splay heuristic'. Sleator and Tarjan showed that if amortised rather ...
order B. Traversing the forest corresponding to the binary tree in root-last order C. Traversing the forest corresponding to the binary tree in breadth-first order D. None of the above 答案：A 分析：正确答案:A 解析:前序遍历一个二叉树等价于按从树的根部、右子树、右子树查找顺序查找树。
