对字符串切片进行排序：按字母顺序*在*降序后的字母

Question

给定：alphanumeric := ["aaa","bbb","ccc","111","222","333"]排序后：["333","222","111","aaa","bbb","ccc"]尝试内置排序包：sort.Strings(alphanumeric)它很接近，但数字部分将按升序排列["111","222","333","aaa","bbb","ccc"]还：sort.Slice(alphanumeric, func(i, j int) bool {    return alphanumeric[i] > alphanumeric[j]})结果不想要：["ccc","bbb","aaa","333","222","111"]对所有东西都很新，谢谢你的任何提示

sort.Slice(alphanumeric, func(i, j int) bool {

    // check if we have numbers, sort them accordingly 

    if z, err := strconv.Atoi(alphanumeric[i]); err == nil {

        if y, err := strconv.Atoi(alphanumeric[j]); err == nil {

        return y < z

    }

    // if we get only one number, alway say its greater than letter 

    return true

    }

    // compare letters normally 

    return alphanumeric[j] > alphanumeric[i]
