I am learning to write more modern C++, since my C++ is from the 1990s (I'm a C# programmer). I need to get used to the STL algorithms and such. So I tried some kata, summing up numbers in a given range that are divisible by 3 or 5, using new C++11/14/17 stuff.
I know that it can be solved mathematically in O(1), but t... |
I started learning Lua yesterday and wanted to write a quick program as a practice.
It queries an external service for the IP address and country code, and naively check for the existence of network interface names used by VPNs (like Nordvpn or other). It then prints a colored output containing the country flag emoji a... |
Task
Write a program that can generate and manage collections of IDs. The user should determine how long the IDs have to be and what symbols they are composed of.
Design choices made by me
The program functionalities are used via command line arguments
A configuration file determines which scheme the IDs correspond to... |
I'm building a drag and drop sortable list in Javascript. This is what I have so far. Is this a good way to solve the problem? How can I improve my code?
<div id="list">
<ul>
<li data-value="Bananas" draggable="true">Bananas</li>
<li data-value="Keys" draggable="true">Keys</li>
<li data-va... |
This exercise is called PDF Paranoia and it comes from CH 15 of the book Automate the Boring Stuff With Python - second edition. There are two parts to the exercise, which I've separated into two Python files. The code I've provided uses Python 3.10 and PyPDF2 v. 2.10.0.
The instructions are as follows:
Using the os.w... |
Task.
To generate random mazes using backtracking algorithm. User inputs how many vertical and horizontal pathes the maze should have and then the script uses this information to generate a maze.
Evaluation criterion.
Maze creation speed. The script should be fast enough to randomly generate huge mazes as fast as possi... |
This is my custom implementation of a double Linked list. Code is apparently working fine. Need advices on improvement and/or optimization. This is a tiny academic side-project. I am still pretty green to C++ .
Would also want to know what are the differences between all sorts of custom implementations and STL implemen... |
