1678. Goal Parser Interpretation

# 1678. Goal Parser Interpretation#

## 题目 #

You own a Goal Parser that can interpret a string `command`. The `command` consists of an alphabet of `"G"``"()"` and/or `"(al)"` in some order. The Goal Parser will interpret `"G"` as the string `"G"``"()"` as the string `"o"`, and `"(al)"` as the string `"al"`. The interpreted strings are then concatenated in the original order.

Given the string `command`, return the Goal Parser’s interpretation of `command`.

Example 1:

``````Input: command = "G()(al)"
Output: "Goal"
Explanation: The Goal Parser interprets the command as follows:
G -> G
() -> o
(al) -> al
The final concatenated result is "Goal".
``````

Example 2:

``````Input: command = "G()()()()(al)"
Output: "Gooooal"
``````

Example 3:

``````Input: command = "(al)G(al)()()G"
Output: "alGalooG"
``````

Constraints:

• `1 <= command.length <= 100`
• `command` consists of `"G"``"()"`, and/or `"(al)"` in some order.

## 解题思路 #

• 简单题，按照题意修改字符串即可。由于是简单题，这一题也不用考虑嵌套的情况。

## 代码 #

``````package leetcode

func interpret(command string) string {
if command == "" {
return ""
}
res := ""
for i := 0; i < len(command); i++ {
if command[i] == 'G' {
res += "G"
} else {
if command[i] == '(' && command[i+1] == 'a' {
res += "al"
i += 3
} else {
res += "o"
i ++
}
}
}
return res
}
``````
