PAT1054. The Dominant Color (20)

题目地址:http://pat.zju.edu.cn/contests/pat-a-practise/1054

此题没有怎么难的,用下map就行了。

代码如下:

//#include "StdAfx.h"
#include<stdio.h>
#include<string>
#include<map>
#include<iostream>
#include<cstring>
#include<stdlib.h>
using namespace std;

int main()
{
	//freopen("D://test.txt","r",stdin);
	map<char*,int> color_count;
	int M,N;
	scanf("%d %d",&M,&N);
	int total=M*N;
	int total_temp=total;
	char color[20];
	while(total_temp--){
		int i;
		scanf("%s",&color);
		++color_count[color];
	}
	int max_count=0;
	char *dominant_clor;
	map<char*,int>::iterator it= color_count.begin();
	for(;it!=color_count.end();++it){
		if(max_count<it->second){
			max_count=it->second;
			dominant_clor=it->first;
			if(max_count*2>total)
				break;
		}
	}
	cout<<dominant_clor<<endl;
	return 0;
}
