    int arr[10000];
    int n, m;
    while (scanf("%d%d", &n, &m) != EOF)
    {

        for (int i = 0; i < n; i++)
        {
            arr[i] = 1;
        }
        int i = 0; int num = 1; int out = 0;
        while (out < n - 1)
        {
            if (num == m)
            {
                out += 1;
