题目：
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, 800×600), 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 (≤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^​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.

Sample Input:

    cin>>M>>N;
    for(int i=0;i<N;i++)
    {        
        for(int j=0;j<M;j++)
        {
            int num;
            cin>>num;
            if(times[num])times[num]++;
            else times[num]=1;
            res=times[num]>times[res]?num:res;
        }
    }
    cout<<res<<endl;

    return 0;
