Combined Exercise #2

Let's do one more!

In this exercise, combine LINQ method calls together to do the following:

Reduce the provided list of words to only those that contain the lower-case letter 'e' in them
Sort the resulting list by alphabetical order
Obtain the last word in the sorted list
Return the string, "The last word is <word>", using the last word from the sorted list
If the sorted list is empty, return null

Combined Exercise 2

using System.Collections.Generic;
using System.Linq;
namespace AllTogether1
{
    public class FullExercise2
    {
        // Given a sequence of words, get rid of any that don't have the character 'e' in them,
        // then sort the remaining words alphabetically, then return the following phrase using
        // only the final word in the resulting sequence:
        //    -> "The last word is <word>"
        // If there are no words with the character 'e' in them, then return null.
        //
        // TRY to do it all using only LINQ statements. No loops or if statements.
        public static string GetTheLastWord(IEnumerable<string> words)
        {
            return words
                // .???().???() ... .???()
                ;
        }
    }
}
