Lets say i have a list of string arrays like ["bbb", "eee", "hhh"], ["ccc", "fff", "iii"], ["aaa", "ddd", "ggg"]

How can i sort the list so that its alphabetical after the first element in each array Like: ["aaa", "ddd", "ggg"], ["bbb", "eee", "hhh"], ["ccc", "fff", "iii"] with selection sort?

Hi robin,

You can use following code to achieve this.Here i am using jagged arrays.
static void Main(string[] args)
        {string[][] arr = { new string[]{ "bbb", "eee", "hhh" },
                         new string[] { "ccc", "fff", "iii"},
                         new string[] { "aaa", "ddd", "ggg"} };
            SelectionSort(arr);
            for(int i=0;i
            {
                for(int j=0;j
                {
                    Console.Write(arr[i][j]);
                }
                Console.WriteLine();
            }
            Console.ReadLine();

        }
public static void SelectionSort(string[][] arr)
        {
            int sizeOfArray = arr.Length;
            int minimum;

            for (int i = 0; i < sizeOfArray - 1; i++)
            {
                minimum = i;

                for (int j = i + 1; j < sizeOfArray; j++)
                {

                    if ((string.Compare(arr[j][0], arr[minimum][0]) < 0))
                        {
                        minimum = j;
                    }
                }

                string[] temp = arr[minimum];
                arr[minimum] = arr[i];
                arr[i] = temp;

            }
        }
