Passes tests but ends with code 132. What's the problem?

Question

C++ / C#

The essence of the task is to create a spiral, for example like this:
1 2 3
8 9 4
7 6 5 - This is a spiral for n=3.

Here is the code I wrote:

vector<vector<int>> create_spiral(int n)
{
  int row = n, col = n; //  длина строк и столбиков
  vector<vector<int>> result; // возвращаемое значение
  int** arr = new int* [n]; // динамический массив, для того чтобы ставить n кол-во инициализаторов 
  for (int count = 0; count < n; count++)
    arr[count] = new int[n];
  int u = 0, r = 1, d = n - 2 , l = n - 1, count = 1; // все переменные, которые нам понадобятся: 
  for(int i = 1; i<=n/2; i++ )                        //u = up(верхний моток),  
  {                                                   // r = right(правый моток), d = down(нижний моток),
    for (int i = u; i <= row-1; i++)                //l = left(левый моток), count = число от 1 до n
      arr[u][i] = count++;                       // n/2 - общее число мотков, то есть при n=4, 
    for (int i = r; i <= col-1; i++)               //мы сделаем только 2 мотка,
      arr[i][row - 1] = count++;                   // при n=3 один моток и последнее число пишем отдельно
    for (int i = d; i >= u; i--)
      arr[d+1][i] = count++;
    for (int i = l - 1; i > u; i--)
      arr[i][u] = count++;
    u++;
    r++;
    d--;
    l--;
    row--;
    col--;
  }
  if (n % 2 != 0) // если n нечетное, то последнее число дописываем отдельно
  {
    arr[n / 2][n / 2] = n * n;
  }
  for (int i = 0; i < n;i++) // передаем значения динамического массива в result, через вектор, 
  {                           //который очищается при каждой итерации
    vector<int> agg;
    for (int b = 0; b < n;b++)
      agg.push_back(arr[i][b]);
    result.push_back(agg);
    agg.clear();
  }
  for (int i = 0; i < n; i++) // удаляем динамический массив
    delete[] arr[i];
  delete[] arr;
  return result;
}

The code works, all spirals turn out as they should. However, when I put it in codewars, it passes both tests and ends up with code 132. I decided to change the code to see what n gives codewars for tests. The first one is 1 and the second one is 2. Pasted the same values ​​in visual studio and it still works fine and there is no 132 code. Actually what is the essence of the question. What could potentially cause code 132 to appear in codewars? Could there be a problem in codewars itself? I have been studying programming for a relatively short time, so please be understanding.

Answer 1

Doesn't pass the 3rd test. And there are 4 of them. I tweaked it a bit, all 4 passed for me.
In the third test, the wrong value of n is given. It needs to be done properly.
