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≤T≤10
1≤N≤105
1≤A[i]≤109
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.
