nodes

问题 I'm implementing a simple linked list and to denote the fact that there is no next node, I'm using the value Nil . The thing is that when assigned to a container, Nil will attempt to revert the container to its default value which means I need to use the container's default value or Any to determine if the linked list's end has been reached. However, I'd still like to use Nil (if only for its clear intent) and no other value to test for the non-existence of a next node in the code (e.g.,

问题 I've found this answer that is coded in C# to plot nodes in a radial tree and gained a lot of information. The problem is that I am having a hard time reading C# and can't exactly figure out the entirety of what's going on. The goal is to try and render a radial tree like the image below, into a game and dynamically show and hide the points based on progress. The majority of radial trees I see use networkx or matplotlib , but I don't want to bloat the game with packages when I only need to

问题 First, I defined my node using a struct called listrec. So each node has 3 parts: prev (used to store the address of the previous node), value (used to store the value), and next (used to store the address of next node). #include <iostream> using namespace std; struct listrec { struct listrec *prev; float value; struct listrec *next; }; listrec *head, *tail; Then, I used a loop to initialize the linked list (based on the number of nodes requested by the user. for (float i = 0; i < number; i++

问题 I've just started learning about graphs, and something that's confusing me is why we need to use external data structures (like matrices or lists) to store which vertexes of the graph are connected to other vertices. Why can't each vertex just hold references to the vertices its connected to, like the way nodes do in a decision tree? That, to me, seems more intuitive. Thanks! 回答1: Well, this comes from a design philosophy. Whenever you have a many to many relationships, you introduce a broker

问题 I want to accomplish, through a script using the Jenkins API, the equivalent of manually clicking on the "Disconnect" link on the node management page in Jenkins. I want to add this code to a script I made using the Pipeline scripting plugin. In other words, as a user with Jenkins admin privileges, do Manage Jenkins -> Manage Nodes -> Click on a node -> Click on "Disconnect" As in: I do not want to do the equivalent of "temporarily mark this node as offline". That is not useful to me. 回答1: I

问题 Long story short, I'm supposed to make a code that inserts, deletes, searches for and prints numbers in a skip list with the first node being negative infinity and the last node being positive infinity (-inf > (...) > inf). I called my search function from my insert function to find a spot to insert any new nodes (only after the third node has been inserted) and I initialize or reference my nodes outside the main function rather than inside of it (although I'm debating on whether or not I
