Geometric Shapes POJ – 3449 Question link: https://vjudge.net/problem/POJ-3449 Question meaning: I will give you many pictures. Each picture has many shapes, including triangles (given the coordinates of three points), squares (given the coordinates of two diagonal points), rectangles (given the coordinates of three points), and line segments (given the coordinates of three points). Two point […]

Linux shell calculates the union, intersection, and difference of two files
Suppose we now have two files a.txt and b.txt The content in a.txt is as follows: a c 1 3 d 4 The content in b.txt is as follows: a b e 2 1 5 #Example 01 Compute the union: [root@VM_81_181_centos ~]# sort -u a.txt b.txt 1 2 3 4 5 a b c d […]
[Algorithm Training – Linked List 3] [Special Linked List] Circular Linked List, Circular Linked List II, Palindrome Linked List, Intersecting Linked List
Without further ado, just shout a slogan to encourage yourself: Programmers will never be unemployed, programmers go to architecture! The theme of this blog is [Judgment related to linked lists], which is implemented using the basic data structure of [linked lists]. The site for this high-frequency question is: CodeTop, and the filtering conditions are: Target […]
Calculate the intersections and intersection sequence of the route planning route
1. Algorithm background At present, many projects require the ability to plan routes. There are many open source map SDKs or paid SDKs that can achieve this. The user selects the starting point, end point and route points to plan the route the user wants, but the ability to identify intersections is average. It is […]

Find the intersection, difference and union of two object Lists based on their attributes – General plus version
Background Based on work needs, Code Brother wrote a solution method for the intersection, union, and complement of List objects a long time ago (the intersection and difference set of two object Lists are obtained based on attributes), and found that many friends have similar needs, and Code recently happened to When I have time, […]
