It feels like this could be much more elegant at places but not exactly sure how. I'm mainly trying to improve how the code almost repeats for getters and s...
Previous question: Pong game in Python with tkinter
This code is almost same as the last code, but it also has a score system. But it also has a few more bugs and takes more time to run.

This is an interview question. Take a list of strings that represent port ranges like these:
const systemPorts = '11000-11001, 11100-11101, 12000-12010, 13000';
const customerports = '11000-11003, 11100-11106, 12000-12015, 13000-13003';
And return a merged list of ports in the form of a stri...
I'm working on a design for a video buffer in C++ that will be used by many consumers both in the native library space(C++) as well as Java side using JNI. My Idea is the following:
