题目描述
Vlad went into his appartment house entrance, now he is on the 1 -th floor. He was going to call the elevator to go up to his apartment.
There are only two elevators in his house. Vlad knows for sure that:
- the first elevator is currently on the floor a (it is currently motionless),
- the second elevator is located on floor b and goes to floor c ( b=c ). Please note, if b=1 , then the elevator is already leaving the floor 1 and Vlad does not have time to enter it.
If you call the first elevator, it will immediately start to go to the floor 1 . If you call the second one, then first it will reach the floor c and only then it will go to the floor 1 . It takes ∣x−y∣ seconds for each elevator to move from floor x to floor y .
Vlad wants to call an elevator that will come to him faster. Help him choose such an elevator.
输入格式
The first line of the input contains the only t ( 1≤t≤104 ) — the number of test cases.
This is followed by t lines, three integers each a , b and c ( 1≤a,b,c≤108 , b=c ) — floor numbers described in the statement.
输出格式
Output t numbers, each of which is the answer to the corresponding test case. As an answer, output:
- 1 , if it is better to call the first elevator;
- 2 , if it is better to call the second one;
- 3 , if it doesn't matter which elevator to call (both elevators will arrive in the same time).

说明/提示
In the first test case of the example, the first elevator is already on the floor of 1 .
In the second test case of the example, when called, the elevators would move as follows:
- At the time of the call, the first elevator is on the floor of 3 , and the second one is on the floor of 1 , but is already going to another floor;
- in 1 second after the call, the first elevator would be on the floor 2 , the second one would also reach the floor 2 and now can go to the floor 1 ;
- in 2 seconds, any elevator would reach the floor 1 .
In the third test case of the example, the first elevator will arrive in 2 seconds, and the second in 1 .
