Maya Calendar
During his last sabbatical, professor M. A. Ya made a surprising discovery about the old Maya calendar. From an old knotted message, professor discovered that the Maya civilization used a 365 day long year, called Haab, which had 19 months. Each of the first 18 months was 20 days long, and the names of the months were pop, no, zip, zotz, tzec, xul, yoxkin, mol, chen, yax, zac, ceh, mac, kankin, muan, pax, koyab, cumhu. Instead of having names, the days of the months were denoted by numbers starting from 0 to 19. The last month of Haab was called uayet and had 5 days denoted by numbers 0, 1, 2, 3, 4. The Maya believed that this month was unlucky, the court of justice was not in session, the trade stopped, people did not even sweep the floor.

For religious purposes, the Maya used another calendar in which the year was called Tzolkin (holly year). The year was divided into thirteen periods, each 20 days long. Each day was denoted by a pair consisting of a number and the name of the day. They used 20 names: imix, ik, akbal, kan, chicchan, cimi, manik, lamat, muluk, ok, chuen, eb, ben, ix, mem, cib, caban, eznab, canac, ahau and 13 numbers; both in cycles.

Notice that each day has an unambiguous description. For example, at the beginning of the year the days were described as follows:

1 imix, 2 ik, 3 akbal, 4 kan, 5 chicchan, 6 cimi, 7 manik, 8 lamat, 9 muluk, 10 ok, 11 chuen, 12 eb, 13 ben, 1 ix, 2 mem, 3 cib, 4 caban, 5 eznab, 6 canac, 7 ahau, and again in the next period 8 imix, 9 ik, 10 akbal . . .

Years (both Haab and Tzolkin) were denoted by numbers 0, 1, : : : , where the number 0 was the beginning of the world. Thus, the first day was:

3
10. zac 0
0. pop 0
10. zac 1995

3
3 chuen 0
1 imix 0
9 cimi 2801

使用了map　大家都什么更好的办法做从字符串到数字的映射

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

typedef map<string,int> STR2INT;

void main()
{
	STR2INT Haab;
	char* str1="pop,no,zip,zotz,tzec,xul,yoxkin,mol,chen,yax,zac,ceh,mac,kankin,muan,pax,koyab,cumhu,uayet,";
	char ch;
	string str;
	int idx=0,m=0;
	while((ch=str1[idx++])!='\0')
	{
		if(ch==',')
		{
			Haab.insert(STR2INT::value_type(str,m++));
			str="";
		}
		else
			str+=ch;
	}
	char Tzolkin[20][10]={"imix","ik","akbal","kan","chicchan","cimi","manik","lamat","muluk","ok","chuen","eb","ben","ix","mem","cib","caban","eznab","canac","ahau"};
	int c;
	cin>>c;
	cout<<c<<endl;
	for(int i=0;i<c;i++)
	{
		int day,year;
		cin>>day>>ch>>str>>year;
		int t=365*year+20*Haab.find(str)->second+day;
		cout<<t%260%13+1<<' '<<Tzolkin[t%260%20]<<' '<<t/260<<endl;
	}
}
