用C#找出最大子分式，求完整代码

class MyMath
    {
        public static List<List<int>> DivideList(List<int> list)
        {
            List<List<int>> newList = new List<List<int>>();
            List<int> subList = new List<int>();
            subList.Add(list[0]);
            for (var i = 1; i < list.Count; i++)
            {
                if (list[i] > list[i - 1])
                {
                    subList.Add(list[i]);
                }
                else
                {
                    newList.Add(subList);
                    subList.Clear();
                    subList.Add(list[i]);
                }
            }
            newList.Add(subList);
            return newList;
        }
        public static List<int> GetLongestList(List<List<int>> newList)
        {
            List<int> list = new List<int>();
            list = newList[0];
            for (var i = 1; i < newList.Count; i++)
            {
                if (newList[i].Count > list.Count)
                {
                    list = newList[i];
                }
            }
            return list;
        }
        public static List<int> GetLongestListFromList(List<int> list)
        {
            return GetLongestList(DivideList(list));
        }
    }
