Today is rose day, batch mates of Kabir and Tara decided to celebrate this day by exchanging roses with each other. 
Note:$Note:$ exchanging means both the boy and the girl will give rose to each other. 
In the class there are B$B$ boys and G$G$ girls. 
Exchange of rose will take place if and only if at least one of them hasn't received a rose from anyone else and a rose can be exchanged only once.
Tara has to bring maximum sufficient roses for everyone and is confused as she don't know how many roses to buy.You are a friend of Kabir, so help him to solve the problem so that he can impress Tara by helping her. 

-----Input:-----
- First line will contain T$T$, number of test cases. 
- Each test case contains two space separated integers B$B$ (Number of boys) and  G$G$ (Number of Girls).

-----Output:-----
For each test case, output in a single line the total number of roses exchanged.

-----Constraints:-----
- 1≤T≤105$1 \leq T \leq 10^5$
- 1≤B≤109$1 \leq B \leq 10^{9}$
- 1≤G≤109$1 \leq G \leq 10^{9}$

-----Sample Input:-----

2 3

-----Sample Output:-----
8
