Mike , intelligent person , challenges his friend suzan with a mathematics task. Whereas, Mike has a list of integers Number N and he has another integer number S . Mike challenges suzan in whether it is possible to obtain the first two numbers in the list, the sum of which is equal to the number S, S = 8 represent the sum of first two number in list , N = 4 is the number of elements in the list . List = 4 5 3 4 , from this ex: first two number = 5 3 .

Input Format

first line there will be an integer number T (number of test cases) followed by 2 input lines for each test case: On the first line of each test case, there will be 2 integers S and N, where S is the expected sum and N is the number of elements in the list. On the second line, there will list of number .

Constraints

1T1000

Output Format

If there is an unique solution: Write two elements, x and y of the list List , such that x+y = S and xy. If there is no solution: Print the error message !NO
