Hi All,

 Request your help in finding duplicate element without sorting 
as per the below example


```
Example:
string[] args = [" test3", "test2 ", " test1 ", " test1 ", " "];

Output Required:
If duplicate element found then print "Duplicate element found: 
"

else print ["test3", "test2", "test1"];

Another approach would be using a rbtree as container at the 
first place.
