What does it mean?

Есть ли скрипт, позволяющий сравнивать пользователей в виде таблицы по задачам с "+"("АС") - решена, "-"(WA5, TL12 ...) - не решена, " " - не пробовал? Или что-то в этом духе? Простите, за мои плохие знания английского языка.
Is there a script that allows you to compare users in the form of a table for tasks with "+" ("as") - solved, "- "(WA5, TL12 ...) - not solved, "" - not tried? Or something like that? Sorry for my poor English skills.

Use printf("%.0lf\n",  floor(answer + .5)); for output answer ;)

I don’t understand what is the mistake here. Help pls
              string[] val = Console.ReadLine().Split(' ');

               double[] k = new double[10000];

              for(int i = 0; i < Convert.ToInt32(val[1]); i++)
               {
                   string s = Console.ReadLine();
                   k[Convert.ToInt32(s) - 1]++;
               }
               double swap = 0;
               for(int i = 0; i < k.Length-1; i++)
               {
                   for(int j = i + 1; j < k.Length - i - 1; j++)
                   {
                       if (k[j+1] > k[j])
                       {
                           swap = k[j+1];
                           k[j+1] = k[j];
                           k[j] = swap;
                       }
                   }
               }
               for (int i = 0; i < Convert.ToInt32(val[0]); i++)
               {

                   Console.WriteLine(string.Format(CultureInfo.InvariantCulture, "{0:N2}", (100 * k[i]) / Convert.ToDouble(val[1]))+"%");
               }

In python 3.6 extra print() in the end of the program gives you WA2. Therefore you should output
"8
 1 3 4 2 0 1 3 2"
instead of
"8
 1 3 4 2 0 1 3 2
 "

a = int(input())
b = int(input())
print(a+b)

Try this:
#X#
#OO
XOX

I spent two hours finding this stupid mistake. Do not be like me, do everything with a margin.

I can't figure out where my mistake is. Can someone give me some tests?

If it is impossible to find out the distance from C to D, then write "Impossible." and not "Impossible"

Seems an easy problem, but I can't understand it...
