大概POJ上50道比较难的题的代码

#include <iostream>
#include <map>
using namespace std;
int main(){
    map <char,char> a;
    char c;
    for(char i = 'a';i <= 'z';++i){
        scanf("%c",&a[i]);
        a[i-'a'+'A'] = a[i] - 'a' + 'A';
    }
    string s;
    getline(cin,s);
    getline(cin,s);
    for(int i = 0;i < s.size();++i)
        if(s[i] >= 'a' && s[i] <= 'z' || s[i] >= 'A' && s[i] <= 'Z') s[i] = a[s[i]];
    cout << s << endl;
}
