思路

暴力模拟，判断好左括号就行，左括号下一个是a就加入al，否则加入o

代码

class Solution {
public:
    string interpret(string command) {
        string res = "";

        for (int i = 0 ; i < command.size(); i++) {
            if (command[i] == 'G') res += command[i];
            else if (command[i] == '(') {
                if (command[i + 1] == 'a') res += command.substr(i + 1, 2);
                else res += 'o';
            }
        }
        return res;
    }
};
