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
