请你设计一个可以解释字符串 command
的 Goal 解析器 。command
由 "G"
、"()"
和/或 "(al)"
按某种顺序组成。Goal 解析器会将 "G"
解释为字符串 "G"
、"()"
解释为字符串 "o"
,"(al)"
解释为字符串 "al"
。然后,按原顺序将经解释得到的字符串连接成一个字符串。
给你字符串 command
,返回 Goal 解析器 对 command
的解释结果。
示例 1:
输入:command = "G()(al)" 输出:"Goal" 解释:Goal 解析器解释命令的步骤如下所示: G -> G () -> o (al) -> al 最后连接得到的结果是 "Goal"
示例 2:
输入:command = "G()()()()(al)" 输出:"Gooooal"
示例 3:
输入:command = "(al)G(al)()()G" 输出:"alGalooG"
提示:
1 <= command.length <= 100
command
由"G"
、"()"
和/或"(al)"
按某种顺序组成
