Roman numerals are represented by seven different symbols: I, V, X, L, C, D and M.
在这里,我整理出一份个人最喜欢的 NPM 软件包清单。为了便于浏览,我还对它们进行了分类,希望呈现出更加清晰的结构。
Problem Description The Romans used letters from their Latin alphabet to represent each of the seven numerals in their number system. The list below shows which letters they used and what numeric value each of those letters represents:
这一次的作业除了关注函数式编程之外,也增加了递归的考察。我个人觉得也是学习和理解递归的一个非常不错的案例。

开发人员通常需要将十进制数转换为二进制、八进制、十六进制或其他进制。由于这是一个常见的任务,在互联网上有很多例子是如何做到的。你可以很容易地找到很多十进制到二进制,十进制到八进制,十进制到十六进制,等等,但是很难找到一个更通用的转换器,可以转换一个十进制数到任何其他进制。这就是我在这篇文章中要向你们展示的。该实现方法可以将任意十进制数转换为2到36进制的任意进制。
ROT13 密码是最简单的加密算法之一,代表“旋转 13 个空格”密码将字母A到Z表示为数字 0 到 25,加密后的字母距离明文字母 13 个空格: A变成N,B变成O,以此类推。加密过程和解密过程是一样的,这使得编程变得很简单。然而,加密也很容易被破解。正因为如此,你会经常发现 ROT13 被用来隐藏非敏感信息,如剧透或琐事答案,所以它不会被无意中读取。更多关于 ROT13 密码的信息可以在en.wikipedia.org/wiki/ROT13找到。如果你想更一般地了解密码和密码破解,你可以阅读我的书《Python 密码破解指南》(NoStarch 出版社,2018)。
