13.7 实例：回文
我们已经展示了足够多的技术示例！让我们尝试一个小小的难题。回文（plaindrome）是一种单词，它顺序拼写和逆序拼写的结果是相同的。例如，anna、petep和malayalam都是回文，而ida和homesick不是回文。有两种方法判断一个单词是否是回文：
获得单词逆序拼写的副本，并将其与原单词进行比较。
判断单词的首字符与尾字符是否相同，然后判断第二个字符与倒数第二个字符是否相同，继续比较下去直到到达单词的中央。
在这一节中，我们将采取第二种方法。根据单词表示方式的不同以及跟踪字符比较进度方式的不同，我们可以通过多种方式实现这一思路。我们将编写一个检测单词是否是回文的小程序，它将采用不同的实现方法，以观察不同的语言特性是如何影响代码的形式和工作方式的。
