对字符串切片进行排序：字母按字母顺序在降序数字之后

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)

很接近，但数字部分将按升序排列

["111","222","333","aaa","bbb","ccc"]

还有：

sort.Slice(alphanumeric, func(i, j int) bool {
    return alphanumeric[i] > alphanumeric[j]
})

结果是不需要的：["ccc","bbb","aaa","333","222","111"]

对所有东西都很陌生，感谢您的任何提示

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]
})
