Lexicographically sorted list of lists of strings

Question

Currently, I am trying to implement a code to generate frequent sequences. In doing so I need to get an in-place sort of a list of lists of strings as follows:

You can try below code:

        List input1 = new List() { "a", "b", "d" };
        List input2 = new List() { "a", "b", "c" };

        //Instead of adding input as List, add it as string
        string delimiter = ",";
        var input1Str = input1.Aggregate((i, j) => i + delimiter + j);
        var input2Str = input2.Aggregate((i, j) => i + delimiter + j);

        var myListStr = new List();
        myListStr.Add(input1Str);
        myListStr.Add(input2Str);

        myListStr.Sort();
        //Now you can convert it into List>
        List> myList = myListStr.Select(x => x.Split(',').ToList()).ToList();
