Input: 

1
6 2
2 1 2 3 4
=
2 2 3 4 5
<

Output:
0
Answer:
5
Checker Log:
Wrong answer expected '5' found '0'

Your output: 0
Correct output: 5

UPD: Udebug says your output is correct, I don't know why though,
The first weighing means that the first 4 coins are correct,
The second weighing is between [2 3] and [4 5] , 2,3, and 4 are correct coins. which means that 5 is incorrect. Please correct me if I am wrong

    Thanks for the help. Logically yes the answer should be 5 but I don't know why it's showing the output to be 0.

"Print a blank line between datasets." I would suggest you to use uDebug: https://www.udebug.com/UVa/665, a very nice tool for uva problems
