        <p>If I have any comments or comments on your program, I will write them and you will be able to see them. Firstly, they will appear on the site in the right column in the "Comments" section; secondly, in each submission, in the window opened by clicking the submit link, there is a special "comments" tab; finally, there is a separate Comments section in the lefthand menu. Accordingly, as soon as I comment on your package, you will see a comment. Usually I try to view all the submissions during the day, although sometimes there are long delays, up to several days.</p>

        <p>In addition to actually writing a comment, I make a decision on each of your submissions — either I accept this submit (albeit with small comments), or I will require you to rewrite this submit taking into account my comments. In the first case, I change the status of the submission to "Accepted" (i.e. you will see exactly "Accepted" instead of "OK" in the table with your submissions), in the second case I change the status to "Ignored". Accordingly, in the first case, just take note of the comments that I wrote (and it happens that I do not write any comments), although you can rewrite the solution if you want. In the second case, be sure to rewrite the solution taking into account these comments.</p>
        <p>(<a href="https://blog.algoprog.ru/why-ignore/">Read more about why I ignore decisions</a> (in Russian).)</p>

        <p>In the summary table, the "OK" solutions (i.e., which I haven't looked at yet) are displayed with a yellow background, the "Accepted" solutions (i.e., which I have accepted) are displayed with a green background, ignored solutions are not taken into account in the total number of problems you have solved, just the corresponding problem in the summary table is displayed with a blue background.</p>


        <p>But in general, try to check the problem before sending it to the system (and we will learn this separately). Treat failed attempts as a real failure, and try to make as few failed attempts as possible. In general, at many programming contests you will have only one opportunity to submit the problem, and if it does not pass some tests, then you will no longer have the opportunity to improve!</p>

        <h3>Accepting and ignoring submits, comments on submits</h3>
        <p>I will review all your solutions: if I have time, all submissions in general, including unsuccessful ones, or if I have little time, and there are a lot of submissions, then only submissions with the OK status.</p>

        <p>In successful submissions, I will review your code for the following:
