Problem Statement

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?

Input

<dl> <dt>The input is given from Standard Input in the following format:</dt> <dt>N M</dt> <dt>a_1 b_1</dt> <dd> <dl> <dt>a_N b_N</dt> <dt>c_1 d_1</dt> <dd>c_M d_M</dd> </dl> </dd> </dl>

Output

Print N lines.
The $i-th line (1 \leq i \leq N)$ should contain the index of the checkpoint for the i-th student to go.

Constraints

  • $1 \leq N,M \leq 50$
  • -$10^8 \leq a_i,b_i,c_j,d_j \leq 10^8$
  • All input values are integers.

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.
