There is a cricket match going on between two teams A and B.

Team B is batting second and got a target of X runs. Currently, team B has scored Y runs. Determine how many more runs Team B should score to win the match.

Note: The target score in cricket matches is one more than the number of runs scored by the team that batted first.

------ Input Format ------ 

- The first line of input will contain a single integer T, denoting the number of test cases.
- Each test case consists of two space-separated integers X and Y, the target for team B and the current score of team B respectively.

------ Output Format ------ 

For each test case, output how many more runs team B should score to win the match.

------ Constraints ------ 

$1 ≤ T ≤ 10$
$50 ≤ Y < X ≤ 200$

----- Sample Input 1 ------ 
4
200 50
100 99
130 97
53 51

----- Sample Output 1 ------ 
150
1
33
2

----- explanation 1 ------ 
Test case $1$: The target is $200$ runs and team $B$ has already made $50$ runs. Thus, the team needs to make $200-50 = 150$ runs more, to win the match.

Test case $2$: The target is $100$ runs and team $B$ has already made $99$ runs. Thus, the team needs to make $100-99 = 1$ runs more, to win the match.

Test case $3$: The target is $130$ runs and team $B$ has already made $97$ runs. Thus, the team needs to make $130-97 = 33$ runs more, to win the match.

Test case $4$: The target is $53$ runs and team $B$ has already made $51$ runs. Thus, the team needs to make $53-51= 2$ runs more, to win the match.
