Alice is playing Air Hockey with Bob. The first person to earn seven points wins the match. Currently, Alice’s score is *A* and Bob’s score is *B*.

Charlie is eagerly waiting for his turn. Help Charlie by calculating the minimum number of points that will be further scored in the match before it ends.

- The first line of input will contain an integer
*T*— the number of test cases. The description of*T*test cases follows. - The first and only line of each test case contains two space-separated integers
*A*and*B*, as described in the problem statement.

For each test case, output on a new line the minimum number of points that will be further scored in the match before it ends.

- 1≤
*T*≤50 - 0≤
*A*,*B*≤6

**Test case 1:** The current score is 0−0. If either Alice or Bob scores 7 consecutive points, then the score will become 7−0 or 0−7 respectively, and the game will end. It can be proven that at least 7 points will be further scored in the match before it ends.

**Test case 2:** The current score is 2−5. If Bob scores 2 consecutive points, then the score will become 2−7 and the game will end. It can be proven that at least 2 points will be further scored in the match before it ends.

**Test case 3:** The current score is 5−2. If Alice scores 2 consecutive points, then the score will become 7−2 and the game will end. It can be proven that at least 2 points will be further scored in the match before it ends.

**Test case 4:** The current score is 4−3. If Alice scores 3 consecutive points, then the score will become 7−3 and the game will end. It can be proven that at least 3 points will be further scored in the match before it ends.
