这个题看着虎,其实还是很水。。。。但因为阅读理解,坑了一些时间。难得这么大的比赛有两道不用脑子的水题。。。

描述上亮点颇多:

1、Mom thinks that pants-shoes pair is disharmonious because
Adiwang is much better than Nike.
(囧RZ)

2、Next
P lines each line will be one of the two forms“clothes x pants y”
or
“pants y shoes z”.(这说明只有两种情况 没有clothes和shoes一起不和谐的情况)

3、For
each case, the first line contains 3 integers N,M,K(1≤N,M,K≤1000) indicating the number of clothes, pants and shoes.
Second line contains only one integer P(0≤P≤2000000)
indicating the number of pairs which mom thinks disharmonious.(注意200000,这说明不用按部就班的模拟,否则TLE)

明白了这些,AC便指日可待了……

1TLE(200000纯属坑爹的) 1WA(数组初始化开错了) 1AC:

#include <iostream>
#include <string>
#include <cstring>
using namespace std;

const int INF=1005;
int clothes[INF],pants[INF],shoes[INF];

int main()
{
	int yi,ku,xie;
	while(cin>>yi>>ku>>xie && (yi!=0 || ku!=0 || xie!=0))
	{
		for(int i=0;i<=INF;i++)
		{
			clothes[i]=0;
			pants[i]=0;
			shoes[i]=0;
		}
		int hexienum,result=0;
		cin>>hexienum;
		if(hexienum==0)
		{
			cout<<yi*ku*xie<<endl;
			continue;
		}
		else
		{
			for(int i=0;i<hexienum;i++)
			{
				
			
			string opa,opb;
			int buhexie1,buhexie2;
			cin>>opa>>buhexie1>>opb>>buhexie2;
			if(opa=="clothes" || opb=="clothes")
			{
				clothes[buhexie2]++;
			}
			if(opb=="shoes" || opa== "shoes")
			{
				shoes[buhexie1]++;
			}
			
			}
			
			
			for(int i=1;i<=ku;i++)
			{
				result+=(xie-shoes[i])*(yi-clothes[i]);
			}
			
			cout<<result<<endl;
		}
		
		
		
		
		
		
	}
	
	
	
	return 0;
}
