Algorithm high-frequency interview: merge K ordered linked lists

High frequency algorithm interview: judge whether the linked list has links?

Finally understand the inverted single linked list

In this technical topic, the reverse technique of single linked list is discussed. The reverse operation includes defining the traversal pointer current and the pre pointer prive, and realizing the flip of each node through the pointer operation. The detailed steps include locating the next node of current, exchanging the current and prive pointers, and finally moving the prive and current pointers to the next node. By repeating this process until the end of the linked list, the entire linked list is inverted. The computer terminal output is prive, because it will become the new head node after inversion. This kind of technical content is suitable for people who have some knowledge of data structure, have programming foundation or are interested in algorithm implementation.

Algorithm high-frequency interview: find the entry point of the ring linked list

This video introduces a method to find the ring node in the linked list data structure. When there is a ring in the linked list, it is the core problem to identify and find the starting node of the ring. The video uses fast and slow pointer technology for cycle detection; When two pointers meet in the ring, a new pointer is introduced to start from the head node. This paper discusses in detail how to move the new pointer and the slow pointer synchronously until they meet. At this time, the meeting point is the incoming node. The logic of the demonstration is clear, the method is efficient, and it is suitable for developers who are pursuing algorithm efficiency and performance optimization. In addition, the graphical aids provided help to understand the derivation process. The video content is suitable for developers, algorithm learners, data structure analysts and technicians in related fields interested in linked lists and their algorithms.

Python crawler: basic usage of Requests library

This content focuses on using Python's requests library to crawl web page data. This paper introduces the applicability and convenience of requests library as an HTTP library without transgenic technology in the process of human obtaining web page data. The video explains how to install the library and how to use the GET method to obtain web objects. It also includes the explanation of HTTP status codes, which help developers identify the response status of HTTP requests. It emphasizes the importance of text coding, and it is necessary to set appropriate coding when processing crawled text data to avoid garbled code. In addition, the video provides a concrete code example demonstration of extracting web page text information through the requests library, which is intended to help developers understand how to use this tool to extract data.

Learn C++from Teacher Wang: divide and conquer algorithm

Divide and conquer algorithm is a powerful skill, which plays a key role in solving complex problems. This abstract focuses on the application of divide and conquer algorithm in C++, emphasizes its characteristic of decomposing large problems into small problems that can be solved independently, and points out the importance of combining function design. Recursive functions are commonly used in this process. They can be combined with parallel computing to make tasks such as array sorting and searching more efficient. Typical practical application scenarios include database query and web crawler. In these scenarios, large-scale data processing becomes easier to manage through divide and conquer algorithm, and processing speed is also improved. This algorithm not only reduces the complexity of the problem, but also shortens the solution time. For C++developers who want to improve the efficiency of data processing, it is crucial to master the divide and conquer algorithm.
