A-Star | A * pathfinding library in Swift | Networking library

I have a form component in React that I use to send data to a pg database.

This is my form script :

I made a sidebar and when I need to scroll down (i just putted some "< br >" on html to test the scroll) the sidebar ends at some point, I want to be able to see the background until the bottom of the page

How can I do that? Here is a quick gif too see what is happening: https://i.gyazo.com/f08b7fbf0592a89bc08da7e2625a86f1.mp4

This is the CSS

I am trying to create a star widget. I have a state array for each star, but when I click one of the stars, ALL of the stars set themselves to that state. I am very lost on this, please halp. I have added a lot of debugging logs. The moment I set newStars[i] = currentStar;, the entire newStars array gets updated, but I'm failing to see why.

Also, here is the code pen link: https://codepen.io/trismi/pen/zYZpvQq?editors=1111

HTML:

I have a code that is used to select certain elements, the code works great when you onSelect and it shows the right option value. The problem is I am not sure how to show the selected option when we search a value onSelect of the dropdown then it's not working.

Here is my Jsfiddle

I have a value res.rating.value and I want to show font awesome stars for this value. Like if the value is 2 then 2 stars will show in the div. I have the following code but whenever I run it the appendChild function shows the error failed to execute parameter 1 is not of type 'Node'

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 have an online course with a difficulty rating that is displayed as a variation of the following:

I am trying to traverse html using jQuery .

You can see the html code in the image. when I hover the mouse over a star the code is triggered

the code finds the span two levels up using parent().parent(). and then gets all the fa-star elements using jquery "find" method. when I loop the code I expect the loop to print 5 items. but it prints about 24 of them.

what can be the cause of this behaviour?

This is the javascript code I use,

I'm new to Laravel coming from PHP core I'm trying to load data from the database in my header.blade.php which is included in app.blade.php.

Do I have to return the header data variable in every view? Do I have to write the same code in every controller function which is returning a view?

If there is another way to achieve that please let me know.

Currently, I have loaded data to my dashboard but it is only available to the dashboard. Please help me out.
