Problem Statement

翻译中…

There are $N$ students and $M$ checkpoints on the $xy$-plane. The coordinates of the $i$-th student $(1 \leq i \leq N)$ is $(a_i,b_i)$, and the coordinates of the checkpoint numbered $j$ $(1 \leq j \leq M)$ is $(c_j,d_j)$. When the teacher gives a signal, each student has to go to the nearest checkpoint measured in Manhattan distance. The Manhattan distance between two points $(x_1,y_1)$ and $(x_2,y_2)$ is $|x_1-x_2|+|y_1-y_2|$. Here, $|x|$ denotes the absolute value of $x$. If there are multiple nearest checkpoints for a student, he/she will select the checkpoint with the smallest index. Which checkpoint will each student go to?

The Manhattan distance between the first student and each checkpoint is: - For checkpoint $1$: $|2-(-1)|+|0-0|=3$ - For checkpoint $2$: $|2-1|+|0-0|=1$ The nearest checkpoint is checkpoint $2$. Thus, the first line in the output should contain $2$. The Manhattan distance between the second student and each checkpoint is: - For checkpoint $1$: $|0-(-1)|+|0-0|=1$ - For checkpoint $2$: $|0-1|+|0-0|=1$ When there are multiple nearest checkpoints, the student will go to the checkpoint with the smallest index. Thus, the second line in the output should contain $1$.
