is trying to turn this into a canonical 2D rage problem, so we're going to set TL = 2 * runtime of fastest solution. You can help us set TL by either submitting faster solutions, or send in more test cases. promises that if the TL goes under 1s at some point, he will bring 3-D rage problems onto Dmojistan.

Deruikong is a highly skilled Minecraft player. Just as he had finished his great wool masterpiece, black holes suddenly appeared and started destroying everything! Acting fast, Deruikong started collecting his blocks so that he could rebuild elsewhere. However, some of the blocks were already too close for him to collect without the risk of getting sucked in. The safeness of any location is the minimum of over all black holes such that , or if no such hole exists. With only 1 hp left, Deruikong needs you to calculate the safeness of each block's location before everything is lost!

No 2 black holes are in the same location.

#### Input Specification

The first line contains two space-separated integers, and .

The next lines contain three integers each, , , and , the location of the th black hole.

The next lines contain three integers each, , , and , the location of the th block.

#### Output Specification

Provide the safeness of each block.
