Monk just purchased an array $$A$$ having $$N$$ integers. Monk is very superstitious. He calls the array $$A$$ Lucky if the frequency of the minimum element is odd, otherwise he considers it Unlucky. Help Monk in finding out if the array is Lucky or not.
Input:
First line consists of a single integer $$T$$ denoting the number of test cases.
First line of each test case consists of a single integer $$N$$ denoting the size of array $$A$$.
Second line of each test case consists of $$N$$ space separated integers denoting the array $$A$$.
Output:
For each test case, print "Lucky" (without quotes) if frequency of minimum element is odd, otherwise print "Unlucky"(without quotes). Print a new line after each test case.
Constraints:
$$1 \le T \le 10$$
$$1 \le N \le 10^5$$
$$1 \le A[i] \le 10^9$$
In first case, value of minimum element is $$5$$ and it's frequency is $$1$$ which is odd, so the array is Lucky.
In second case, value of minimum element is $$3$$ and it's frequency is $$4$$ which is even, so the array is Unlucky.
