如果 s2 是一个 slice，你可以将 s2 向后移动一位 `s2 = s2[1:]`，但是末尾没有移动。slice 只能向后移动，`s2 = s2[-1:]` 会导致编译错误。slice 不能被重新分片以获取数组的前一个元素。 如果 s2 是一个 slice，你可以将 s2 向后移动一位 `s2 = s2[1:]`，但是末尾没有移动。slice 只能向后移动，`s2 = s2[-1:]` 会导致编译错误。slice 不能被重新分片以获取数组的前一个元素。

因为字符串是纯粹不可变的字节数组，它们也可以被切分成 slice。 因为字符串是纯粹不可变的字节数组，它们也可以被切分成 slice。
