I have been working on code splitting for my implementations and I ended up having 3 different approaches to do it. The reason why I did something like this is that I also worked as a front-end developer and I did code-splitting for a Webpack project because it can create multiple bundles that ca...

I am currently trying to replicate the stl std::list interface with my own list implementation (doubly linked list with sentinel) to learn about all the advanced topics (like iterators, allocators, ...). Before I add the methods from the "operations" section in the documentation, I'd love to hea...

I am solving one question in which I need to find two number sum out of an vector input from the terminal. For instance if I input vector of integers - {1,-1,4,6,2,5,8} and my sum is 10 - it should return pairs {4,6} and {2,8} but my code below returns only {4,6}. I am just not able to get how to...

I've been recently fooling around with Go(lang) and ended up doing a (very) simple pig Latin parser. I'm pretty sure this is not the best solution out there (no punctuation and only lowercase letters) but it does its job. However, I'd be delighted to learn how this could be improved, as I'm stil...

In some legacy code I have inherited, there is a snippet that looks similar to this. List<Callable<String>> callableStrings = Arrays.asList("one", "two", "three").stream() .map(s -> (Callable<String>) () -> s) .collect(Collectors.toList()); List<String> results = someExe...
