基于字符串创建的切片和原字符串指向相同的底层字符数组, 字符串的切片操作返回的子串仍然是string,而非slice。切片数组返回的是,slice,但是底层指向 数组
To convert a string into array of characters (which is slice of runes) in Go language, pass the string as argument to []rune(). This will create a slice of runes where each character is stored as an element in the resulting slice. ...
