Good Day! I'm currently trying to create a database that needs me to create two ADT. One of them has a private struct linkedlist created in this example

The problem is I can't seem to access or at least print out the values inside my struct in a function from another class

here is a sample code I derived from my original

I have to create a service availability using info from this 2 query.

First Query.

Thanks for looking into this, I was trying to make a visual simulation of Depth first search algorithm, using graphics.h in C++, Each of my graph nodes have 3 attributes, x_coordinate y_coordinate and a nodeId, also I have a separate Class for Graph Object which has the adjacentcy list graph, So As the following code was executed It gave The results as incomplete, one of the five edges in input ( Input given below ) edge ( 0 - 3 ) was not displayed See snap shot here , can you help me with this?

So basically my code iterates through the list and the original method is supposed to return the linked list however it doesn't seem to be adding the nodes that I link in the recursive method and I'm confused as to why. Can anyone help me?

I created a generic linked list in C to store data of any type. That involves, of course, using the void pointer. I know the code is working generally, but my problem is probably due to memory management surrounding the void pointer to store an array of chars (ie C strings). Probably due to my lack of deep understanding of void pointers in C?

It is best to show my problem using code examples below for testing purposes.

I am writing a university project, where I take two algorithms and compare their performance, the main algorithms are Dijkstra and A*, however I am not very experienced with either Vue.js, JS in general and algorithms, and my first iteration of Dijkstra is SUPER slow. I am using a 2D grid of X by Y, with a start point node and an end point node, and running the algorithm. Any grid above 10x10 is completely too slow.

I am at a loss on what to do, I don't see any errors when running the code, it executes, but executes entirely too slow. I am not very experienced, so I don't know where to start to look and what the issue could be. Maybe there's someone with experience that could help out and tell me what I'm doing wrong?

I have a table with column cDate.

I want to calculate the time difference between two consecutive record with the same cRt value.

E.g.:

Take a look at following code and output:

I am pretty new to delphi development, I have a custom CheckTreeList component inherited from cxTreeList Devexpress component. When i check some nodes in a list, Those values are stored to a string in a format as shown below String Format for selected nodes as image The issue is I am not able to check the nodes of the checktreelist by looping through the nodes and values in the string. I have tried the below code for saving and loading the checked and unchecked nodes. Saving the checked node key values to string is working, But Loading the nodes and checking them is not working. The below is the component source code
