    int[] x = {5, 2, 3, 6, 5};
    int n = x.length;

    for (int j = n-2; j > 0; j--)
      x[j] = x[j-1];

    for (int j = n-1; j >= 0; j--)
      System.out.print(x[j]);
  }
}

c.

class Driver {
  public static void main(String[] args) {
    int a = 3;

    for (int c = 1; c < 6; c++) {
      b = 1;
      while (b < c) {
        a = a + 2;
        b = b + a;
      }

  }
}

d.
