Thanks for the response Ken. I have tried 3 ways but all of them throwing error:

1). As suggested: 

@{$difference[0]}

[download]
Error -- >Can't use string ("ARRAY(0x2c992e0)") as an ARRAY ref while 
+"strict refs" in use at

[download]

2). Tried 2nd way 

@{$difference}

[download]
Error as below -- > 
Global symbol "$difference" requires explicit package name at 
Global symbol "$intersect" requires explicit package name at 
Global symbol "$union" requires explicit package name at .

3). tried 3rd way 

@difference

Expected output should be device names(e.g ..ABC-DCFE41->90) so that I can remove difference part one by one from the data set.
