BFS | Behrooz File System | File Utils library

I have a react app that has a NavBar and a grid system. This NavBar shows some information and has buttons to run the application and the grid system contains the functions and visualizes the application. I want to have the NavBar button click trigger a function to call in the grid system component, specifically the animateAlgorithm function. As you can see, I already have a provider that shares some state information between these two components. What I don't understand is how to make it call the function.

I am newly learning Python, and I am trying to create a bfs algorithm that can take vertices of a weighted graph and return the bfs. Eventually, I will need to add the weighted edges to the vertices so that I can calculate the distance travelled, however I am able to get the bfs to work with my vertices alone. This is the code so far:

The documentation here https://neo4j.com/docs/graph-data-science/1.1/algorithms/bfs/#algorithms-bfs describes a callable "gds.alpha.bfs.stream".

In order to call that, to the best of my knowledge, it needs to be registered with the embedded DB. Something along the lines of

I have this function:

I'm a first year student who's learning Julia as a first programming language. I have a project about bellman ford's algorithm but it seems every code is a bit more advanced than I can currently understand. Is there a basic code like Dfs or Bfs for this that a starter could understand, if u have, do share.

I'm doing some graph exercises in C and was confused by the sample solutions. I've attached my code below with additions from the sample solutions I don't understand yet.

My question is why in the sp_algo function multiple declaration and initialization of struct queueNode adjCell; and struct Point new_point; works? On the other hand, if I, for example, declare and initalize struct Point end = {2, 6}; in the main function twice, it returns an error:

When I run my code it throws a segmentation fault and I have tried rewriting the code several times. Still to no avail, it won't even run. The segmentation fault happens as soon as my program is launched. What it's supposed to do is print a path on screen using the ncurses library in Linux, from the given coordinates. Here is the problematic snippet with the lines where gdb said the segmentation fault was, also it (snippet) reproduces the problem.

EDIT: This will help explain what I'm trying to do, but using dynamic arrays. Breadth First Search

EDIT 2: The variable frontier is supposed to keep track of the X and Y values at a specific index. The add_neighbors function is there to add all four neighbors (providing they aren't already added) to the frontier and came_from arrays.

frontier[index][0] is X value.
frontier[index][1] is Y value.

The before the first while loop I set the start position x1 and y1. During the first while loop, it increments getting the new coordinates from the frontier, then processing and adding to came_from array.

For example:
(x1,y1) (x1+1,y1)
(x1,y1+1) (x1+1,y1+1)
(x1,y2) (x2,y2)

I'm trying to get from (x1,y1) to (x2,y2). Sure hope that explains it better. What I'm trying to implement is a Breadth First Search (BFS) algorithm. Using two arrays, one is frontier (keeps track of visited positions) and came_from (keeps track of X and Y the path from x1,y1 to x2,y2). Updated the code to reflect the first answer. Plus added a comment to explain where the error might be, not really sure but I've been debugging it. It looks like the came_from array never gets set with x and y.

The Code:

I try to fetch object vorlagen with ID 6310 from this API and want to show if property vorlageAngenommen is true or false.

The JSON object looks as follows:

My code that does not run, looks as follows (I am not sure if this is a good base at all):

I'm trying to import this XML https://wmts.geo.admin.ch/EPSG/2056/1.0.0/WMTSCapabilities.xml into google spreadsheets using the IMPORTXML function . using XPATH I would like to extract from
