@文心快码set remove time complexity java 文心快码 1. 集合(Set)数据结构的基本概念 集合(Set)是Java中的一种基本数据结构,用于存储不重复的元素。在Java中,Set接口继承自Collection接口,是一种不包含重复元素的集合。它允许使用equals()方法来判断集合中的元素是否相等。Set接口的实现类主要包括HashSet、LinkedHash...
list:list/dict都可以从指定位置删,list简单直接给pop(index)即可 set:set其实有pop,但它既不能指定,且没有所谓最后一个,也是随机,其他得用remove或者discard(区别在于如果元素不存在,前者会报错而后者不会) dict: 根据官网来看,dict的复杂度平均是O(1),最坏的结果才是O(n)。只是占内存一些,dict的pop比较特殊...

TreeSet is implemented using a tree structure(red-black tree in algorithm book). The elements in a set are sorted, but the add, remove, and contains methods has time complexity of O(log (n)). It offers several methods to deal with the ordered set like first(), last(), headSet(), ...
With sorted sets you can add, remove, or update nodes in a very fast way (in a time proportional to the logarithm of the number of nodes). You can also get ranges by score or by rank (position) in a very fast way. Accessing the middle of a sorted set is also very fast, so ...
