<h1>1054. The Dominant Color (20)</h1>
|
|
<div id="problemContent">
|
|
<p>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 <i>strictly</i> dominant color takes more than half of the total area. Now given an image of resolution M by N (for example, 800x600), you are supposed to point out the strictly dominant color.</p>

Input Specification:
|
|
</b></p>
|
|
<p>Each input file contains one test case. For each case, the first line contains 2 positive numbers: M (<=800) and N (<=600) which are the resolutions of the image. Then N lines follow, each contains M digital colors in the range [0, 2<sup>24</sup>). It is guaranteed that the strictly dominant color exists for each input image. All the numbers in a line are separated by a space.</p>

Output Specification:

<p>For each test case, simply print the dominant color in a line.</p>
