I often see nested loops as a solution to the bubble sort, but my solution involves a recursive function. Is the following solution less efficient than the traditional method? public static int[] BubbleSort(int[] arrayOfValues) { var swapOccurred = false; for (var i = 0; i < arrayOfV...

I have been trying to learn c++ for the sake of being comfortable with a second language. I found a project that seemed relatively easy, although it may not be implemented perfectly, it was a simple project. I create a std::map<double, std::string>, which will represent the tax rate as a double, ...

I have been building an application to scrape prices from a "rooms for rent" website and average them to help out new movers. All the work is done, however, currently the code only scrapes the one page I gave it, I'm trying to get it to scrape the next page and so on until it has all avaliable pr...

I've started to get far more familiar with C (and coding in general) and the way to use function to my advantage to create more complex programs. As a way of doing something actually useful instead of my "Starting Programming with C: For Dummies" book I decided to make a simple program to help me...

How does the following look to list the directories on a posix system? This is actually the first piece of C code that I've written where I've actually been able to use for a real-world problem! #define _GNU_SOURCE #include <dirent.h> #include <string.h> #include <fcntl.h> #include <stdio.h> #inc...

I am a total beginner in Python and I am trying with the modules Turtle. I am currently trying to code for 3 sliders (R, G, B) for adjusting the colors of the turtle screen. However, I found parts of my codes filled with redundancies, could anyone please tell me how to trim the code to make it mo...

I've created a simple lambda function that polls a few websites periodically to see if something changed. One way it does this is by making a hash of the page and seeing if it different than the original hash, provided by a json file, like so: { "check_type": "hash", "url": "https://www.h...

I am trying to write a benchmarking tool from scratch in python. Unfortunately, no matter how I try, my code can not reach the performance of other benchmarking tools like wrk/wrk2. Using wr2 I can make 42k reqs/s while my code can create only up to 2200 reqs/s. I have tried multiple ways to para...

I am trying to find a N number of leading zeros from the output of the sha1 hash function. I would like N to go up to 10 or 9. Currently I can get to 7 in about 7 minutes (even though is not always that fast), but already 8 takes forever. The input to the sha1 must be a combination between an inp...

This is an updated version of my first question: Chess game in Kotlin I wrote the following Chess logic in Kotlin and am looking for feedback to make the code cleaner and follow good software design principles. I tried to adhere to object-oriented design. Some notes and questions I still have: • ...

I created a contact form with flexbox. It uses the mobile-first approach so everything inside the media query is for large screen. :root { box-sizing: border-box; } *, *::before, *::after { box-sizing: inherit; } body { margin: 0; padding: 0; } .contact-container { max-width: 120...

I have the following bit of code in a service worker that checks to see it the url contains any of the values in an array and if so it breaks out of the function. As it is run for every asset on a webpage, it can be run a lot of times so I was wondering if this was the best way to do it or if it...

I'm currently creating a terminal-based RPG like Pokémon as a learning project so my programming skills are limited. My main problem right now is stat management of the player. My code works like this: I have a Player class which creates characters. Its constructor has parameters for character i...

To improve my Python knowledge I started a small coding project: A telegram chat/quiz bot that is based on official questions about basketball rules. The bot reads them from one or multiple .csv files. I tried to seperate game logic and chat interaction as good as possible, but failed somewhat. I...

I am making a simple file explorer with tkinter Python. This is the file repository on github. I know that this is pretty much long code and it took that much time to write but i have somehow added the comments. And I want someone to test my code. Also the additional mechanisms are not here and t...

I am developing a system for runtime macro executions in an automatic test environment. Macros are defined in an xml and are for configuring multiple devices/DUTs for a specific use case. The xml parsing of these macros is outside of the scope of this question. For building the macros in code I c...

After I have been doing some improvements from my Previous code review. I have taken the knowledge to upgrade and be a better coder but now im here again asking for Code review where I think it could be better. The purpose of this code is a monitoring that checks for a special site every random 3...

i am kind of new to low level designing, need your feedback on this design of Chess game. dont go inside the core logic, just provide your comments based on the design part. the class 'Chess' receives calls from the UI to move the Pieces. this class has a Board object and 2 Player objects. the Bo...

Currently working on a pre-solve collision library. My goal is to have it be potentially usable in potential video game projects of mine, so time constraint is small as this should be used in a game loop: this algorithm currently takes too long. I am aware of broadphasing, but I believe there is...

The purpose of this code is to use it to calculate some number theoretic function efficiently for the numbers from 1 to 1000000, but I am not sure if it will be really useful. The main purpose was to program a piece of C++ code because I have almost no experience in this language. So it would be...

Improve hash Set List filtering UI Data that gets saved as a HashSet. These respond to the PriorityCode values of 1-9 in the database. This code all works fine and is according with the business rules, but however. This seems to be a terribly inefficient way to do this. How can this be improved?...

I have this code: Sorted=False while not Sorted: Sorted=True for x,y in enumerate(List[:-1]): if List[x]>List[x+1]: List[x],List[x+1]=List[x+1],List[x] Sorted=False However the use of Sorted=True/False being repeated is quite ugly and it would be much nic...

Been looking into some simple algorithms, I came up with the following piece of code in C to implement the Euclidean algorithm iteratively (I like to be clear here, I don't want the recursive implementation for now). I've seen various other implementations and in fact most books prefer a differen...

I have a problem. It seems very bulky and bad to me and I have to reduce it. I often repeat one and the same function..who can simplify this? private enabledButton(filterData: any) { if (this.checkEqualsDate(filterData)) { return this.removeDate(filterData) } if (this.checkEq...

I implemented a key:value format file parser in C, or something that comes close to it as there is no such thing as dynamically creating structs in C. Assumptions: we are creating a C program that needs some config options (e.g. the number K of threads in a concurrent server that handles requests...
