利用string建立map对应，利用str.find()查找索引

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

int main()
{
    string input,output;
    cin>>input;
    string a={"ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789"};
    string b={"bcdefghijklmnopqrstuvwxyza222333444555666777788899990123456789"};
    for(auto x:input)
    {
        string temp;
        temp=b[a.find(x)];
        cout<<temp;       
    }
}
