Let’s continue our journey towards creating a general library from several algorithms, but today, let’s take a step back from Hacker Rank (since it doesn’t support C++20 yet) and see what we can do to improve our code using the Concept feature

In the following text, I will explore the various modifications that a typical algorithm can undergo during the process of software evolution (restricting myself with C++14, as HackerRank not supporting advanced version and I want to check solutions with that). Spend an hour to make an exact task (and then a day to extend with a feature and ane more deay to allow usage in other code) or a mounth on makeing generous algorithm that can be used in future. Would you rather spend an hour on the code that solves an exact task (and then a day to extend it with a feature, and another day to allow its usage in other code), or spend a month creating a more general code that can be used in the future? That is the question every programmer faces when confronted with a new task. And the answer, as always, is ‘it depends’ (cue eye roll).
