Chessboard Distance

The Chessboard Distance for any two points $(X_1, Y_1)$ and $(X_2, Y_2)$ on a Cartesian plane is defined as $max(|X_1 - X_2|, |Y_1 - Y_2|)$. You are given two points $(X_1, Y_1)$ and $(X_2, Y_2)$. Output their Chessboard Distance. Note that, $|P|$ denotes the absolute value of integer $P$. For example, $|-4| = 4$ and $|7| = 7$. ### Input - First line will contain $T$, the number of test cases
