[Tutor] checking if all items in a list are the same

[Julieta Rangel]

If I have a list, how can I compare all of the elements to check if they are 
the same?  Say that I have the following list:

[e,e,e,e,e]

How can I tell the computer to go item by item in the list and compare them. 
  If they are the same, I want the computer to tell me that it has found the 
identity element, and if they are not the same, I want the computer to tell 
me that there is no identity element. Can anyone help?
