Problem type

Snow White and the dwarfs live in the forest. While the dwarfs mine away Snow White hangs around social networks.

Each morning the dwarfs form a long line and go whistling away to the mine. Snow White runs around them and snaps pictures to upload onto her favorite social network.

When dwarfs enter the mine, Snow White goes back to their house and goes through the pictures, selecting pretty ones. Each dwarf has a colored cap, and there are different colors. A picture is pretty if more than half the caps on it are of the same color. In other words, if there are dwarfs on the picture, it is pretty if strictly more than dwarfs have same colored caps.

Write a program that will check for a set of pictures if they are pretty, and what color is dominating if they are.

#### Input Specification

First line contains two integers and number of dwarfs and number of colors.

Third line contains , number of pictures.

Next lines contain two integers and . Each line describes one picture. On it there are all dwarves starting from -th all the way to the -th.

In test cases worth 30% points, will be smaller than .
In test cases worth additional 30% points, will be smaller than .

#### Output Specification

Output lines. For each picture output no if Snow White doesn't think the picture is pretty, and yes X, where is the color dominating on the picture, if she does.
