1. Definition of bipartite graph A bipartite graph is a special undirected graph whose nodes can be divided into two disjoint sets, so that there are no edges connecting any two nodes in the same set, but there are no edges between nodes in different sets. Connected by edges. In other words, if an undirected […]

Refined solution to the bracket matching problem and ultimate stack design: uncovering the mysteries of the largest stack and the smallest stack
Directory Bracket matching problem Minimum stack Maximum stack Max stack and min stack are two important variants of extreme stack. The max stack is used to store the maximum value of the current match, and the min stack is used to store the minimum value of the current match. Bracket matching problem Let’s take a […]
Harbin Institute of Technology Information Content Security Experiment 3–String Matching
1. Experimental purpose Be familiar with the AC or WM multi-pattern matching algorithm, implement the AC or WM string matching algorithm in a familiar high-level language, and evaluate the space and time complexity 2. Experimental requirements PS. I only did what I had to do and chose the AC [Must Do] 1: Implement the multi-pattern […]

Mastering Python RegEx: A Deep Dive into Pattern Matching
Use your little hands to make a fortune and give it a like! What is a regular expression? Regular expressions, often abbreviated as regex, are powerful tools for processing text. Essentially, they consist of a series of characters that establish a search pattern. This pattern can be used for a wide range of string operations, […]
[AGC034D] Manhattan Max Matching
Problem Statement Snuke is playing with red and blue balls, placing them on a two-dimensional plane. First, he performed $N$ operations to place red balls. In the $i$-th of these operations, he placed $RC_i$ red balls at coordinates $(RX_i,RY_i)$. Then, he performed another $N$ operations to place blue balls. In the $i$-th of these operations, […]
10. Circuit synthesis-wideband matching circuit design method based on simplified real frequency
10. Circuit synthesis-wideband matching circuit design method based on simplified real frequency Chapters 1-9 in the Overview of Network Synthesis and Simplified Real Frequency Theory Learning introduced some basic concepts and experimental methods of SRFT, and finally came to another ultimate use of SRFT, the design of broadband matching circuits. 1. Some previous reviews and […]
Map matching of taxi trajectory data under offline OSM data conditions
Map matching of taxi trajectory data under offline OSM data conditions Preface: In the process of studying the road network matching of Python taxi GPS data (TransBigData + leuvenmapmatching) written by senior Xiaoxu of traffic data, I found that the osmnx library is difficult to obtain a complete road network of a city or a […]
Revealing the Mysterious String Matching Tool-Regular Expressions
Regular expressions, also known as regular expressions (often abbreviated as regex, regexp or RE in code), are a powerful tool for matching, finding, and replacing text. It can automate text processing by matching strings with specific patterns. In many programming languages, regular expressions are widely used in text processing, data analysis, web crawling and other […]
