消化理解:上述代码里,__repr__是Python内置的一个标准定义方法,表示对象自身的执行,因此,只要我们给已经初始化的 llist 进行任意操作,乃至对其内部值进行任意操作,都会触发__repr__的执行。所以,从代码上看,你可能会一头雾水:为什么仅仅只是给第一个Node实例指派了next值,就能改变llist的结果呢?这里需要补充一下...

In Python, there’s a specific object in the collections module that you can use for linked lists called deque (pronounced “deck”), which stands for double-ended queue. collections.deque uses an implementation of a linked list in which you can access, insert, or remove elements from the ...

链表(Linked List)是一种线性数据结构,它由一系列节点(Node)组成,每个节点包含两部分:数据和指向下(上)一个节点的引用(或指针)。链表中的节点按照线性顺序连接在一起(相邻节点不需要存储在连续内存位置),不像数组一样存储在连续的内存位置。链表通常由头节点(Head)来表示整个链表,而尾节点的下一个节点指向null,...
