  {
      //nums.getClass().getTypeName() -> int[]
      int total = 0;
      for (int num : nums ) 
          total += num;
      return total;
  }
  

• C#

  public int Sum(params int[] nums) 
  {
      //nums.GetType() -> System.Int32[]
      int total = 0;
      for (int i = 0; i < nums.Length; i++)
          total += nums[i];
      return total;
  }
  

• Python
