My code doesn't actually do that per se, but rather it find every possible edge that can be added without creating a cycle. The return value of the function FindNodesToConnect is a map, where the key is a node and the value is a list of all the nodes we can direct an edge to from the key without ...

I have written a class that acts like a stopwatch using C++11's std::chrono library. I wrote this because I find it difficult to benchmark my cpp code properly, this class just combines chrono's functionality and gives it a nice interface I have two classes, stopwatch.h and lapwatch.h. The second...

I've implemented a simple vector-like structure. I would appreciate all criticism relevant to code. I have also published code under github. Here is the link to source code + unit test for most functions: https://github.com/Nethius/mystd const double_t expansion_ratio = 1.5; namespace mystd { ...

I am trying make this code run a bit more functional. I want to filter a set of data, and based on the ReportsTo string I am recursively finding the line managers but only if the Rank is not less than 3. This works, but if I try to run it with a map, I can not flatten out the results from the fin...

I am learning Rust and decided to create a simple program to calculate n-th Fibonacci number. It uses a vector for memoization. The program works, but what would you suggest to improve here? Maybe store memo inside fib function as a static variable? I tried to use u32 everywhere, but 48-th fib nu...

I just finished making a simple 1D Chess Game and I was wondering if I could make any improvements to my code to make it run faster or to make it look cleaner I included descriptions of what each file does on the README section of the github repo and I also included comments so as to inform you o...
