strings.trim
strings.trim(string_to_trim, cutset)

形参数据类型
STRING，STRING
返回类型
STRING
代码示例
以下是一些示例用例。
示例 1
在以下示例中，相同的字符串作为输入字符串和 cutset 传递，这会导致生成一个空字符串。
strings.trim("str", "str") // ""
示例 2
在以下示例中，空字符串作为 cutset 传递，这会生成原始字符串 str，因为 cutset 中未指定要移除的字符。
strings.trim("str", "") = "str"
示例 3
在以下示例中，该函数会生成一个空字符串，因为输入字符串已为空，并且没有要移除的字符。
strings.trim("", "str") = ""
示例 4
在以下示例中，该函数会生成 str，因为 trim 函数会移除以下内容：
- “a aastraa aa ”中的尾随空格
- cutset 中指定的字符（空格、a）
strings.trim("a aastraa aa ", " a") = "str"
