I didn’t know how to name this problem, that’s why I named it as it’s written in the post title. This is a problem from another coding test on one of these coding challenge platforms. I still think that these platforms are just an automation of this weird “whiteboard coding” process. And it’s a pity that companies still believe that such tests could indicate really good programmers. Probably I would write a post with my thoughts on this topic later…

First time I faced this problem during one of my codility tests for a work application. And I failed it. :) Just because I have never heard about such problems before. Anyway, my opinion about codility tests is the same as about writing code on a whiteboard.  A programmer should be able to think, to investigate and solve the problem in the end.

Stress not compliment process of thinking, it destroys this process. Well, it’s a topic for another post. In this post, I will provide my investigation on a Knight distance problem and a solution.

I just wanted to display some fancy messages after actions connected with form submission, like auth or change password.

And I have been living this new life in a new city for last 6 years. But Odessa city, which I left, still occupies a big part in my heart.

This is another summary task given by my English teacher. He found a very informative tech magazine, called Open Source for You, which introduces a lot of useful and modern tech content. And this time the summary will be about natural language processing, especially about information extraction technique used by search engines and about a knowledge database canonicalization problem. It’s a very interesting topic for me and I’m thankful to my teacher for giving me such interesting topics for my writing.
