要处理的输入字符串
默认 false,是否将空格作为分隔符之一
splitString("Hello world\nThis is a test\nGood luck!");
/// 返回: ["Hello world", "This is a test", "Good luck!"]
splitString("Hello world\nThis is a\ntest\nGood luck!", true);
/// 返回: ["Hello", "world", "This", "is", "a", "test", "Good", "luck!"]
splitString("Hello\n\n\nworld\n\n", false);
/// 返回: ["Hello", "world"]
splitString("", true);
/// 返回: []
splitString(" ", false);
/// 返回: []
将输入字符串分割为字符串列表,基于换行符、回车符和可选的空格。
