题目如下:
思路:
(1)题目的意思:让我们把十进制转化为十三进制,再把十三进制转化为十进制
(2)需要注意的是,如果转化为十三进制的时候 eg;input 26(13的倍数),那么十三进制为10,重点来了这个时候不是让你输入一零
而是让你输入是十,也就是只输入高位就可以了
代码如下:
#include<cstdio> #include<sstream> #include<iostream> #include<cstring> #include<unordered_map> #include<array> using namespace std; main(){ int n; array<string,13> low={"tret","jan","feb","mar","apr","may","jun","jly", "aug", "sep", "oct", "nov","dec"}; array<string,13> high={"tret","tam", "hel", "maa", "huh", "tou", "kes","hei","elo","syy","lok","mer", "jou"}; // array<int,13> temp; unordered_map<string,int> temp; for(int i=0;i<13;i++) { temp[low[i]]=i; temp[high[i]]=i*13; } cin>>n; string b=""; cin.get(); while(n--){ getline(cin,b); if(isdigit(b[0])) { int c=stoi(b); if(c/13!=0&&c%13!=0) cout<<high[c/13]<<" "; else if(c/13!=0&&c%13==0) cout<<high[c/13]<<endl; if(c/13==0||c%13!=0) cout<<low[c%13]<<endl; } else{ stringstream a; a<<b; int k=0; while(a>>b){ k+=temp[b]; } cout<<k<<endl; } } return 0; }
另外:
如何把字符流中 a空格b转化为ab?
代码如下:
#include<cstdio> #include<sstream> #include<iostream> using namespace std; main(){ string n; getline(cin,n); cout<<n<<endl; stringstream s; s<<n; while(s>>n) cout<<n<<endl; //将a b分开能转换为ab char a; while(cin>>a) cout<<a; return 0; }
