1. Print the following string "abcdefgh" and shift it by one character until completely looped through, example output : abcdefgh bcdefgha cdefghab defghabc etc...

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Exercises
{
    class StringBuilderExercise
    {
        static void Main(string[] args)
        {
            StringBuilder str = new StringBuilder("The Quick Brown Fox Jumped Over The Lazy Dogs");

            // run once through all the characters 
            for (int i = 0; i < str.Length; i++)
            {
                //print the whole string starting from the current char until the char before (loop)
                Console.WriteLine(str);
                str.Append(str.ToString().Substring(0,1));
                str.Remove(0,1);
            }
        }
    }
}

2. - User interactively enters a word then enter - word goes in a queue - list of words is printed - queue size is 5, meaning oldest word gets ditched if the queue is full

namespace Exercises
{
    class QueueExercise
    {
        static void Main(string[] args)

            while (true)
            {
                String typedString = Console.ReadLine();
                queue.Enqueue(typedString);

                // queue should have only 5 elements
                if (queue.Count == 6)
                {
                    queue.Dequeue();
                }

                PrintValues(queue);
            }
        }

        private static void PrintValues(IEnumerable myCollection)
        {
            foreach (Object obj in myCollection)
            Console.Write("    {0}", obj);
            Console.WriteLine();
        }

    }
