WebOct 1, 2011 · MSVC has a hash_set in an earlier implementation. They are likely keeping it for a while to make it easier on developers who used hash_set. MS moved the hash_set out of std and into a the stdext namespace. You should use unordered_set for any new code. The specific algorithm by either will be compiler dependent. – David Nehme Oct 1, 2011 …

Web所谓的HashSet,指的就是 System.Collections.Generic 命名空间下的 HashSet 类,它是一个高性能,无序的集合,因此HashSet它并不能做排序操作,也不能包含任何重复的元素,Hashset 也不能像数组那样使用索引,所以在 HashSet 上你无法使用 for 循环,只能使用 foreach 进行迭代,HashSet 通常用在处理元素的唯一性上有着超高的性能。 … WebDesign a HashSet without using any built-in hash table libraries.
