Given the time control of a chess match as a + b, determine which format of chess out of the given 4 it belongs to. 

1) Bullet if a + b < 3  

2) Blitz if 3 ≤ a + b ≤ 10

3) Rapid if 11 ≤ a + b ≤ 60  

4) Classical if 60 < a + b

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

- First line will contain T, number of testcases. Then the testcases follow.
- Each testcase contains a single line of input, two integers a, b.

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

For each testcase, output in a single line, answer 1 for bullet, 2 for blitz, 3 for rapid, and 4 for classical format.

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

$1 ≤ T ≤ 1100$
$1 ≤ a ≤ 100$
$0 ≤ b ≤ 10$

----- Sample Input 1 ------ 
4
1 0
4 1
100 0
20 5

----- Sample Output 1 ------ 
1
2
4
3
----- explanation 1 ------ 
TestCase $1$: Since $a + b = 1 < 3$, it belongs to bullet format.

TestCase $2$: Since $3 ≤ (a + b = 5) ≤ 10$, it belongs to blitz format.
