Così ora siamo pronti per un quiz per vedere se hai capito le liste nidificate
现在我们进行小测验 看大家是否理解嵌套链表
Per questo quiz, è data una variabile chiamata "countries" [stati]
有一个变量 叫做countries（国家）
definita con una lista di informazioni sulle mie città preferite.
它是一个链表 包含我最喜欢的国家的一些相关信息
E per ciascuno stato, c'è una lista contenente 3 dati:
每个国家都是一个链表 包含三个信息
il nome dello stato, la capitale e la sua popolazione in milioni.
国名 首都 以及人口 以百万计
Devo puntualizzare qui che quelli di voi della Romania o in stati più piccoli,
我要指出的是 对罗马尼亚或者其他一些更小的国家的人来说
che a proposito di stati, più grande non vuol dire sempre meglio.
对于国家 大并不代表好
Primo, prova a scrivere il codice che stampa la capitale dell'India.
首先写下能够打印出印度首都的代码
Possiamo trovare l'India come secondo stato nella nostra lista.
印度是我们链表countries中的第二个国家
E la capitale è il secondo elemento di quella lista.
印度首都是其第二个元素
Potresti risolvere il problema semplicemente stampando "Delhi"
显然大家可以直接打印出Delhi（德里）
ma non voglio che lo risolva così.
但是这不是我们所希望见到的方法
Voglio che lo risolva trovando una espressione che usi la variabile "countries"
我希望大家能够利用countries这个变量写出表达式
e trovi il valore corretto.
来得到正确的值
