PAT甲级1100题（火星数）

1.题目介绍

2.考察点，难度

进制转换，MAP用法，int与string转换，难度易

3.解题代码

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

int main()
{
	string ones[13] = {"tret", "jan", "feb", "mar", "apr", "may", "jun", "jly", "aug", "sep", "oct", "nov", "dec"};
	string tens[13] = {"", "tam", "hel", "maa", "huh", "tou", "kes", "hei", "elo", "syy", "lok", "mer", "jou"};
	map<string, int> M2E;
	for (int i = 0; i < 13; i++) M2E.insert(pair<string, int>(ones[i], i));
	for (int i = 1; i < 13; i++) M2E.insert(pair<string, int>(tens[i], i*13));
	int N;
	cin >> N;
	getchar();
	string s;
	for (int i = 0; i < N; i++){
		getline(cin, s);	// 获得一行输入存入s中 
		if (s[0] >= '0' && s[0] <= '9'){
			int earth = stoi(s);
			if (earth/13) cout << tens[earth/13];
			if (earth/13 && earth%13) cout << " ";
			if (earth%13 || earth == 0) cout << ones[earth%13];
			cout << endl;
		}
		else{
			int earth = 0;
			if (s.length() > 4) earth = M2E[s.substr(0,3)] + M2E[s.substr(4,3)];
			else earth = M2E[s];
			cout << earth << endl;
		}
	}
	return 0;
}
