Elixir standard library provides a whole lot of functions to deal with lists. We will have a look at some of those here.S.no.Function Name and Description 1 delete(list, item) Deletes the given item from the list. Returns a list without the item. If the item occurs more than once ...
Elixir 的串列是用單向連結串列實作的。這意味著取得串列長度會是一個線性時間 O(n) 的運算。由於同樣的原因,通常把新元素插入串列的頭部 (prepend) 會比插入串列的尾部 (append) 更快:iex> list = [3.14, :pie, "Apple"] [3.14, :pie, "Apple"] # Prepending (fast) iex> ["π" | list] ["...
append(tuple, value) 在元组末尾插入元素。 delete_at(tuple, index) 从元组中移除元素。 duplicate(data, size) 创建一个新的元组。 insert_at(tuple, index, value) 将元素插入元组中。 to_list(tuple) 将元组转换为列表 append(tuple, value) 代码语言:javascript 复制 append(tuple,term)::tuple 在元组...

前言:本文是Redis吊打面试官系列的数据结构原理专题,介绍列表list的底层实现 前提认识:Redis的list底层是双向链表 1、链表节点结构 2、list结构 3、总体结构 总结: 链表被广泛用于实现Redis的各种功能,比如列表键、发布订阅、慢查询、监视器等。 通过为链表设置不太的类型特定函数,Redis的链表可以用于保存各种不太类型...
