I wrote a prioritized left shuffle algorithm (the code is copied from my open source C# project Fluent Random Picker). That means: You've got some values and each of them has a priority (a number). The higher the priority is, the higher are the chances of the value being far on the left after the...

Given an integer n, find the median of the list of all integers from 1 to n − 1 that are coprime with n. Recall that integers a and b are called coprime if their greatest common divisor is 1. The median of a list L is defined to be the |L| 2 -th element of L if |L| is even, and the |L|+1 2 -th el...

Im fairly new to tensorflow and following a tutorial to make a linear regression model based on a CSV of titanic survivors.

Below you can see my implementation of a simple event dispatcher. I removed the includes from the files to get a better readability. I would like to get some feedback or improvement tips regarding the design and maybe an idea how to get rid of the static_cast. Thank you very much. Classes Event.h...

This question is with respect to Day 1, Part 2 of the 2021 Advent Of Code challenge, which requires comparing values from a rolling window taken from integers streamed as input. This answer is correct, insofar as it emits the intended output, but I'm unclear as to the quality of the code. (This c...

This Module started as a fun coding exercise designed to emulate the tree command and also calculate the size of each folder based of the files size of that folder (non-recursive). Now, completed and tested on Windows and Linux, I thought it would be nice to have it reviewed to see where it could...
