 题意:字符串数字13进制转换

 

 AC代码

 方法一:循环方式存入 13 * 13 个数后输出

 1 #include<bits/stdc++.h>
 2 using namespace std;
 3 string unit[] = {"tret", "jan", "feb", "mar", "apr", "may", "jun", "jly", "aug", "sep", "oct", "nov", "dec"};
 4 string tens[] = {"tret", "tam", "hel", "maa", "huh", "tou", "kes", "hei", "elo", "syy", "lok", "mer", "jou"};
 5 string numToStr[170];
 6 unordered_map<string, int> strToNum;
 7 int main()
 8 {
 9     for(int i = 0; i < 13; i++) {
10         numToStr[i] = unit[i]; strToNum[unit[i]] = i;
11         numToStr[i*13] = tens[i]; strToNum[tens[i]] = i * 13;
12     }
13     for(int i = 1; i < 13; i++){
14         for(int j = 1; j < 13; j++)
15         {
16             string s = tens[i] +   + unit[j];
17             numToStr[i * 13 + j] = s;
18             strToNum[s] = i * 13 + j;
19         }
20     }  
21     int N; string str;
22     cin >> N;
23     getchar();
24     for(int i = 0; i < N; i++) {
25         getline(cin, str);
26         if(str[0] >= 0 && str[0] <= 9) { int num = stoi(str); cout << numToStr[num] << endl;} 
27         else cout << strToNum[str] << endl;
28     } return 0;
29 }
