Title Description: The two-fork tree is converted into a string using the first-order traversal, where the nodes are separated by parentheses, and the specific examples are shown in the topic link Ideas: First, the value of the root node is converted into a string, and then the value of the left and right subtree is converted to a string recursively. Connecting the root node in 1 to the strings of the left and right nodes is the result, which requires attention:

606 of questions recall, some can remember the options, and some are just the general idea of the question. Let's take a look. 1. in an environment with high security requirements, what does it mean to cancel the access-list setting? I remember two options a. That means the security of access-list settings is canceled. B. It means that the processing delay of the router is low because you do not need to query the ac.

You need to convert a binary tree into a string of parentheses and integers in the way of a pre-order traversal. Empty nodes are denoted by a pair of empty parentheses "()". And you need to omit all empty brace pairs that do not affect the

Must clarify the logic, I in this problem tinkering, hit the patch to play for a long while, finally found that if there is a clear logic at first, then the code will be very simple. Class Solution: def tree2str (self,t): if T is None:
