# 1054 The Dominant Color (20 分)

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

### Input Specification:

Each input file contains one test case. For each case, the first line contains 2 positive numbers:

### 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:

24
思路：map的简单使用

#include<bits/stdc++.h>
using namespace std;
const int maxn=1010;

map<int,int> mp;
int num[maxn][maxn];
int main(){
int m,n;
cin>>m>>n;
for(int i=0;i<m;i++){
for(int j=0;j<n;j++){
cin>>num[i][j];
mp[num[i][j]]++;
}
}
for(map<int,int>::iterator it=mp.begin();it!=mp.end();it++){
if(it->second>=m*n/2){
cout<<it->first<<endl;
}
}
return 0;
}
