I'm a beginner in python programming, been doing it for only a few weeks and I decided to make a tic-tac-toe game in the python interpreter. I'm looking for feedback on the program and any way I can improve it and shorten it and point out inefficiencies/errors since I've done everything I can to ...

As an exercise in using PyQt, the python switch statement and abstract classes, I made a little app to make conversions between geodetic (WGS84) and PSD93 (Oman) and UTM 40N projections (instead of the ubiquitous calculator). The app has a main window and 3 dialog windows; 4 types of conversions ...

I am enjoying making various programs with C++. This is my first code review request. And I hope I can get some insights or might have good advice to make my code better. I make a task class using C++14 standards after having insights of System.Threading.Task class of C#. Although I could not mak...

I recently started to program in Rust, having like 2 good years of experience in C++, I thought it would be possible to directly switch to Rust without following a lot of tutorials, especially knowing that it's mostly math functions that I'm making. So, here is a code that I produced to make Eule...

I have a react native app. I have a search component, that I reuse in the SearchScreen (where I search for train stops) and again in my Report screen where I report (and first search station) not station with issues. I was trying to apply best practices but not sure how well I did. I would really...

https://codeforces.com/contest/1472/submission/173347946 This above link is the first way I've tried solving this problem. I first create a node representing each number inputted. After that, I link the nodes together. I try to optimize this by ignoring nodes that already linked (to prevent repet...

Following is my simple implementation of the std string class. Please review my code and offer some advice. I want to figure out is there anything wrong with my code or is there anything I can improve on my code. #include <iostream> using namespace std; class String{ private: char *buf=nullpt...

I want to load credentials into my program from different sources. If one source does not have 'valid' credentials (in my case valid credentials are all tuples of two non empty strings), try the next source until you get a valid credential (or the sources run out). I wrote a method (validate) tha...
