1. First-First element of sequence
2. Skip-Remaining elements of sequence
3. Reverse-Reverse the sequence
string[] array = new string[] {"aaaa","bbbb","cccc" };
IEnumerable<string> result1 = array.Take(2);
IEnumerable<string> result2 = array.Skip(2);
IEnumerable<string> result3 = array.Reverse();
foreach (string i in result1)
Console.WriteLine(i);
foreach (string i in result2)
Console.WriteLine(i);
foreach (string i in result3)
Console.WriteLine(i);
Console.ReadLine();
