水题，练习下map函数和传递引用，忘了把测试的注释掉WA好久不知道哪里错= =

#include <iostream>#include <map>#include <string>using namespace std;void toup(string &str){int len=str.length();for(int i=0; i < len; i++)if(str[i]>='a'&&str[i]<='z') str[i]=str[i]-32;}int main(){map<char,int>key;key['A']=2; key['B']=2; key['C']=2;key['D']=3; key['E']=3; key['F']=3;key['G']=4; key['H']=4; key['I']=4; key['J']=5; key['K']=5; key['L']=5; key['M']=6; key['N']=6; key['O']=6; key['P']=7; key['Q']=7; key['R']=7; key['S']=7; key['T']=8; key['U']=8; key['V']=8; key['W']=9; key['X']=9; key['Y']=9; key['Z']=9;string str;int test;cin >> test;while(test--){cin >> str;int len=str.length();toup(str);//cout << str << endl;int i,j;for(i=0,j=len-1; i < j; i++,j--){if(key[str[i]]!=key[str[j]]) break;}if(i < j) cout << "NO" << endl;else cout << "YES" << endl;}return 0;}
