NoteLet us demonstrate one of the suboptimal ways of getting a pair $$$(3, 5)$$$: Using an operation of the first type with $$$k=1$$$, the current pair would be equal to $$$(1, 1)$$$. Using an operation of the third type with $$$k=8$$$, the current pair would be equal to $$$(-7, 9)$$$. Using an operation of the seco...

Each test contains multiple test cases. The first line contains the number of test cases $$$t$$$ ($$$1 \le t \le 10^4$$$). Description of the test cases follows. The only line of each test case contains two integers $$$c$$$ and $$$d$$$ $$$(0 \le c, d \le 10^9)$$$, which are William's favorite numbers and which he wants...

For each test case output a single number, which is the minimal number of operations which William would have to perform to make $$$a$$$ equal to $$$c$$$ and $$$b$$$ equal to $$$d$$$, or $$$-1$$$ if it is impossible to achieve this using the described operations.

William has two numbers $$$a$$$ and $$$b$$$ initially both equal to zero. William mastered performing three different operations with them quickly. Before performing each operation some positive integer $$$k$$$ is picked, which is then used to perform one of the following operations: (note, that for each operation yo...
