Very concise and short, but without losing readability - a very talented piece of code-prose!

Generally, your solution is the same as mine, I just don't create a few additional structures, like you do.

Dude, come on... I consider your comment very unethical, unfair and undesirable. This is like jumping the queue. Here are some random principles for reviewing and eventually points giving. Your comment with the appeal for review is disguised begging for some points because you want to attract attention to your solution and hope, that the reviewer gives you some points when he looks on your solution already. According to my point of view, this attracting attention is very unwanted here on comments and I am definitely for avoiding this behavior because comments here are for completely different purposes than for <pre class='brush: python'>"Could you review mine and give me some feedback? Link: ..." </pre> Can you imagine how comment threads look like when everybody here will give comments with the link on his/her solution with appealing for some feedback? In that cases, I try to think about some moral disputes in view of `Categorical imperative` from philosopher Immanuel Kant. <a href="https://en.wikipedia.org/wiki/Categorical_imperative">https://en.wikipedia.org/wiki/Categorical_imperative</a> <pre class='brush: python'>"Act only according to that maxim whereby you can at the same time will that it should become a universal law." Immanuel Kant </pre> So I want to ask you. Do you want to see here on CheckiO also from all other users comments for feedback request? Are these comments still useful? Is this behavior for feedback request, which you want to widespread? I know, we are also competitors for Monthly Leaderboard, but for me it is against the grain to use this method for gaining more points for this Monthly Leaderboard competition and at least in one case you received points for Mind Switcher solution from another user, because you asked for your solution feedback and therefore attract attention of that user for your solution. <pre class='brush: python'>I have doubts whether the points obtained in this way are correct. </pre> In that case, I lost the desire to continue the competition, because I don't want to use the same method to be able to compete. PS: Under every your comment with your feedback request, I will give this comment. PPS: Because I want to know the point of view of other users here in CheckiO, I initiate also debate about this topic on the forum. I want to know, if my point of view is prevailing, or if I am lonely in my opinion. PPPS: This topic contribution can be taken e.g. something as Meta on Stack Overflow, where is discussed, how users want to form rules for the site and so on. PPPPS: It's nothing against you personally, I only want to know what is wanted and unwanted behavior regarding comments here on CheckiO and I also gave my point of view.
