Hashset cpp
WebHashSet (); Creates an empty HashSet of the specified element type. You may also optionally provide an initializer list of values. The newly created set will contain those values. Usage: HashSet set; HashSet set = { value1, value2, value3 }; Method detail void add (const ValueType& value); WebHashSet TreeSet 2.基本的使用 3.无序 无重复 无序：我们使用集合存放元素的顺序 集合内取出来的顺序不一致 集合本身是有自己的算法排布顺序 hash算法 HashSet---->(HashMap (数组+链表) 散列表 临接连表)
