PAT甲级——A1054 The Dominant Color

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 Mby N (for example, 8), 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 (≤) and N (≤) which are the resolutions of the image. Then N lines follow, each contains M digital colors in the range [0). 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:

5 3

0 0 255 16777215 24

24 24 0 0 24

24 0 24 24 24

Sample Output:

 #include <iostream>

 #include <vector>

 #include <unordered_map>

 using namespace std;

 int main()

 {

     int M, N;

     cin >> M >> N;

     unordered_map<int, int>res;

     vector<vector<int>>data(M, vector<int>(N, ));

     for (int i = ; i < N; ++i)

     {

         for (int j = ; j < M; ++j)

         {

             int a;

             cin >> a;

             res[a]++;

             if (res[a] > M*N / )

             {

                 cout << a << endl;

                 break;

             }

         }

     }

     return ;

 }
