Behind the scenes in the computer's memory, color is always talked about as a series of 24 bits of information for each pixel. In an image, the color with the largest proportional area is called the dominant color. A strictly dominant color takes more than half of the total area. Now given an image of resolution $M$ by $N$ (for example, $800\times 600$ ), you are supposed to point out the strictly dominant color.

Input Specification

Each input file contains one test case. For each case, the first line contains 2 positive numbers: $M$ ( $\le 800$ ) and $N$ ( $\le 600$ ) which are the resolutions of the image. Then $N$ lines follow, each contains $M$ digital colors in the range [ $0, 2^{24}$ ). It is guaranteed that the strictly dominant color exists for each input image. All the numbers in a line are separated by a space.

Output Specification

For each test case, simply print the dominant color in a line.
