[ABC057B] Checkpoints

Score : 200200 points

Problem Statement

There are NN students and MM checkpoints on the xyxy-plane. The coordinates of the ii-th student (1iN)(1 \leq i \leq N) is (ai,bi)(a_i,b_i), and the coordinates of the checkpoint numbered jj (1jM)(1 \leq j \leq M) is (cj,dj)(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 (x1,y1)(x_1,y_1) and (x2,y2)(x_2,y_2) is x1x2+y1y2|x_1-x_2|+|y_1-y_2|. Here, x|x| denotes the absolute value of xx. 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?

Constraints

  • 1N,M501 \leq N,M \leq 50
  • 108ai,bi,cj,dj108-10^8 \leq a_i,b_i,c_j,d_j \leq 10^8
  • All input values are integers.

Input

The input is given from Standard Input in the following format:

NN MM

a1a_1 b1b_1

::

aNa_N bNb_N

c1c_1 d1d_1

::

cMc_M dMd_M

Output

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

The Manhattan distance between the first student and each checkpoint is:

  • For checkpoint 11: 2(1)+00=3|2-(-1)|+|0-0|=3
  • For checkpoint 22: 21+00=1|2-1|+|0-0|=1

The nearest checkpoint is checkpoint 22. Thus, the first line in the output should contain 22.

The Manhattan distance between the second student and each checkpoint is:

  • For checkpoint 11: 0(1)+00=1|0-(-1)|+|0-0|=1
  • For checkpoint 22: 01+00=1|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 11.

There can be multiple checkpoints at the same coordinates.
