You shouldn’t be printing those arbitrary statements like “Enter the number of test cases”. It’s a machine checking your answer so just print either “yes” or “no”

3

Where are you checking that elements [1,7] are compulsarily there?

You are failing here-

Input
1
13
1 1 1 1 1 1 1 1 1 1 1 1 1
Your output
yes
Expected Output
no
