The following code interweaves two linked lists together in three flavors: iterative, recursive top-down, and recursive bottom-up. My iterative solution feels like it can be optimized better and my bottom up recursive design skills are not necessarily the best (although this solution is a much sm...
I tried to help someone in Stackoverflow with a refactoring exercise. Did many changes to his original code and made a somewhat decent solution (at least in my eyes). Was thinking, whether someone can critique on my implementation.
In my previous question, I got heaps of good advice BUT no solution for the problem apposed.
I applied the valuable learnings from the past on this.question and am also hitting it from a different angle.
The second part is the reason I didn't mark the question as 2.0 version of the first but fe...
I am aware that most 'generic' BFS algorithms that use a queue also check for uniqueness of visitation to 'speed things up' as it were, but I'm a bit unclear as to how to implement such a method as I'm still a newbie to graph theory. Beyond any general critique, I am curious how to modify the idd...
I'm a self-tought programmer. That means I've hit a lot of walls until I managed to create something interesting. One of the thickest walls was the code structure. These are the practices I tried to overcome it:
Single-file program. This practice works pretty good when main.cpp is under 1000 li...
I needed to convert a formatted file size back into its length in bytes. I came up with the following code but want it reviewed:
/**
* Converts a formatted size to its equivalent in bytes.

* @param size
* The formatted file size. Examples: "125.5 MB", "1KiB", "0.8 GB"
* @retur...
I am using following approach to avoid callback hell. I am curious about what you guys think since I haven´t seen this approach before. What are pros and cons?
To me the advantages are:
Easy to read. From top to bottom with maximum one indention.
Incredibly fast.
The asynchronous functions can...
I have defined the tag that can sit on all the pages of my website and be easily integrated into the admin tool. It is the broadest category with properties that are relevant for all pages.
Can you please tell me if it is written correctly?
I am concerned that the URL code line might be picked ...
I wanted to learn how to create awesome parallax scrolling effects so I decided to look up how to do it, after some searching I put together this test. It works fine to some extent but it feels a bit messy, especially if you would expand it with more effects and elements.
You can see it in acti...
I'm trying to learn how chained hashing works, but can't get any further than this.
I think hashing works, but after finishing this little program, someone told me that what I have created so far has nothing to do with hashing. :/
Here is my code:
#define _CRT_SECURE_NO_WARNINGS
#include <st...
I have a small UI that involves adding roles and modules to a user database array. The interface works as is, no problem at all, but it seems to have a bit of 'duplicate' code that I was hoping I could get some advice on ways to refactor, if at all possible.
function Db() {
var self = this;...
I want to wait for a line to be read, but only for so long before timing out. This is what I came up with. Is there a better way to do it?
Dim reader As New System.IO.StreamReader(pipe)
Dim nextCommand = Await New Func(Of Task(Of String))(
Function()
Dim t = reader.ReadLineAsync()...
The code should be self-explanatory:

I am working on a 2D tile based platformer and was hoping to get someone to review my collision detection. I've only included the X collision check since the Y is essentially the same. Any suggestions/criticisms are appreciated.
// Corrects X movement if a collision occurs.

def current_active_role
user_roles.each do |r|
if r.is_active_role
return r
end
end
return nil
end
The block above returns whatever the user's currently active role is. There are User, UserRoles (lookup table), and Roles tables.
I'm looking for a more concise way to say "go through...
