Deja Vu

You aren't paying attention and you accidentally type a bunch of random letters on your keyboard. You want to know if you ever typed the same letter twice, or if they are all unique letters.

If you are given a string of random letters, your task is to evaluate whether any letter is repeated in the string or if you only hit unique keys while you typing. 
 
Input Format:  
A string of random letter characters (no numbers or other buttons were pressed). 
 
Output Format:  
A string that says 'Deja Vu' if any letter is repeated in the input string, or a string that says 'Unique' if there are no repeats. 
 
Sample Input:  
aaaaaaaghhhhjkll 
 
Sample Output:  
Deja Vu
