Chef has started working at the candy store. The store has 100 chocolates in total.

Chef’s daily goal is to sell X chocolates. For each chocolate sold, he will get 1 rupee. 
However, if Chef exceeds his daily goal, he gets 2 rupees per chocolate for each extra chocolate.

If Chef sells Y chocolates in a day, find the total amount he made.

------ 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 daily goal of Chef, and the number of chocolates he actually sells.

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

For each test case, output on a new line the total amount Chef made in a day.

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

$1 ≤ T ≤ 100$
$1 ≤ X, Y ≤ 10$

----- Sample Input 1 ------ 
4
3 1
5 5
4 7
2 3

----- Sample Output 1 ------ 
1
5
10
4

----- explanation 1 ------ 
Test case $1$: Chef's daily goal was $3$. Since he sold only $1$ chocolate, he'll get only $1$ rupee.

Test case $2$: Chef's daily goal was $5$. Since he sold $5$ chocolates, he'll get $5$ rupees.

Test case $3$: Chef's daily goal was $4$. Since he sold $7$ chocolate, he'll get $4$ rupees for the $4$ chocolates as his daily goal and $2$ rupees per chocolate for the extra $3$ chocolates. The total amount he gets is $4+3\cdot 2 = 10$.

Test case $4$: Chef's daily goal was $2$. Since he sold $3$ chocolate, he'll get $2$ rupees for the $2$ chocolates as his daily goal and $2$ rupees per chocolate for the extra $1$ chocolate. The total amount he gets is $2+1\cdot 2 = 4$.
