Integer Moves
There's a chip in the point $$$(0, 0)$$$ of the coordinate plane. In one operation, you can move the chip from some point $$$(x_1, y_1)$$$ to some point $$$(x_2, y_2)$$$ if the Euclidean distance between these two points is an integer (i.e. $$$\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}$$$ is integer).Your task is to determine the minimum number of operations required to move the chip from the point $$$(0, 0)$$$ to the point $$$(x, y)$$$.
In the first example, one operation $$$(0, 0) \rightarrow (8, 6)$$$ is enough. $$$\sqrt{(0-8)^2+(0-6)^2}=\sqrt{64+36}=\sqrt{100}=10$$$ is an integer.In the second example, the chip is already at the destination point.In the third example, the chip can be moved as follows: $$$(0, 0) \rightarrow (5, 12) \rightarrow (9, 15)$$$. $$$\sqrt{(0-5)^2+(0-12)^2}=\sqrt{25+144}=\sqrt{169}=13$$$ and $$$\sqrt{(5-9)^2+(12-15)^2}=\sqrt{16+9}=\sqrt{25}=5$$$ are integers.
The first line contains a single integer $$$t$$$ ($$$1 \le t \le 3000$$$) — number of test cases.The single line of each test case contains two integers $$$x$$$ and $$$y$$$ ($$$0 \le x, y \le 50$$$) — the coordinates of the destination point.
For each test case, print one integer — the minimum number of operations required to move the chip from the point $$$(0, 0)$$$ to the point $$$(x, y)$$$.
