上述的映射表

string strMap="A    3   HIL JM O   2TUVWXY51SE Z  8 "; 
    
    char mmap(char ch){
    	if(ch>='A'&&ch<='Z'){
    		return strMap[ch-'A'];//字母映射 
    	}else{
    		return strMap[ch-'0'+25];//字符映射 
    	}
    }

#include <bits/stdc++.h>
    using namespace std;
    string strMap="A    3   HIL JM O   2TUVWXY51SE Z  8 "; 
    
    char mmap(char ch){
    	if(ch>='A'&&ch<='Z'){
    		return strMap[ch-'A'];//字母映射 
    	}else{
    		return strMap[ch-'0'+25];//字符映射 
    	}
    }
    
    int main(){
    	string s;
    	while(cin>>s){
    		int len=s.length();
    		bool flag1=true;//回文串
    		bool flag2=true;//为镜像串 
    		for(int i=0;i<(len+1)/2;i++){
    			if(s[i]!=s[len-1-i]){
    				flag1=false;
    			}
    			if(mmap(s[i])!=s[len-1-i]){
    				flag2=false;

    		}
