When you talk about router ACLs, the first thing you think about is the standard ACL and the extended ACL, and actually the little-known named Access ACL. The main purpose of this article is to introduce a named access Control list configuration.

Java Collection of dry goods-inventory list source code analysis, dry goods inventory listPreface
In the previous article, we analyzed ArrayList in detail. Today we will talk about 'arraylist. What is the difference between them? The biggest difference is that the underlying data structure is implemented differently. ArrayList is implemented by arrays (see the previous article), and LinedList is implemented by a linked
In a Word document, when you have multiple, side-by-side information content or paragraphs, we often organize the document in the form of adding item labels, and the document is more aesthetically pleasing to read. In addition, for content with a certain level of logic, you can also use a multilevel numbered list to indicate the level of document content, and also add flexibility when modifying and editing documents. Therefore, in this document, you w

I. Question
This section describes how to allocate and deploy the storage space of elements by linking all unused slots into a free table. Assume that a slot can store a flag and an element with one or two pointers. All dictionary operations and free linked list operations should have the expected o (1) running time. Is the free linked list a double-stranded table? Or is it enough for a single-chain table?
How to convert List
Convert List, string.A List can be converted to a string. This is possible with the ToArray method on the List type. We can also convert a string into a List. ConversionsThe StringBuilder typeHelps with certain conversions, which are done with loops. Whe
This article mainly introduces three methods of traversal (sequence number and value) in the Python List (List) to traverse the sequence number and value in the List:

Given A linked list, remove the nth node from the end of the list and return its head.For example, n = 2. After removing the second node from the end, the linked list becomes 1->2->3->5.Note:Given n would always be valid.Try to do the in one pass.Linked list of a simple topic, the topic requires only one pass to sw
Turn list with parent ID to tree, ID list to tree
We know that databases generally store trees in a list (id,pid). How to extract the tree? The simplest method is to check the table according to the PID loop. But there is no doubt that this creates a huge database query overhead.
Then the general recommended method is to isolate all relevant data at once, but th

Swap nodes in pairs
Given a linked list, swap every two adjacent nodes and return its head.
For example, given1->2->3->4, You shoshould return the list2->1->4->3.
Your algorithm shocould use only constant space. You mayNotModify the values in the list, only nodes itself can be changed.
Note: during the first two SWAps, the head must change its position. There is also a pre pointer.
