Note: all intervals given above are open intervals.
Input
First line is the number of test cases t (t <= 6),
then for each case number of real numbers in the array is given (n)
then in the next line the real numbers are given.
Output
Print the required answer, i.e., "found" or "not found".
Constraints
1 <= n <= 3*10^5
