但是,不应该通过iterator去改变元素值(key),因为会破坏红黑树的排序规则 红黑树的设计本身,并没有要求是否可以重复key值,并且提供了两种insertion操作:insert_unique()和insert_equal() 如果调用第一个并且元素重复,就会安插失败 回到顶部 源码G2.9 key表示关键字类型 value表示key和data合起来的类型 keyofvalue表示如...
Map/Multimap以rb_tree为底层结构,其特点如下: Map、Multiset排序依据为key; map的key必须唯一,其insert为rb_tree的insert_unique();multimap的key可以重复,其insert是rb_tree的insert_equal(); map将key_type设置为const,禁止用户修改key,允许用户修改data; multimap不可使用[ ]做insertion map的实现 底层调用rb_...
loit是 m.entrySet().iterator()，即整个TreeMap的节点指针，如果该迭代器指针不为null，则需要从迭代...
The SPLAY_INSERT() macro inserts the new element elm into the tree. Upon success, NULL is returned. If a matching element already exists in the tree, the insertion is aborted, and a pointer to the existing element is returned. The SPLAY_REMOVE() macro removes the element elm from the tr...
Lookup, insertion, and deletion are performed in O(log N) time in the expected and worst cases. On the other hand, the average case complexity of lookup/insertion/deletion on a Hash is constant time. A Hash is usually faster than a RBTree where ordering is unimportant. The elements of ...
The RB_INSERT() macro inserts the new element elm into the tree. Upon success, NULL is returned. If a matching element already exists in the tree, the insertion is aborted, and a pointer to the existing element is returned. The RB_REMOVE() macro removes the element elm from the tree...
An implementation of a Red/Black Binary Search Tree. Originally created in 2014, this library has been thouroughly tested and battle hardened. Binary search trees exhibit the following characteristics: Insertion: O(log n) Removal: O(log n) Search: O(log n) Thanks go to those responsible for...
