AVL树

      AVL树又称为高度的平衡二叉树,它能保持二叉树高度的平衡,尽量降低二叉树的高度,较少树的平均搜索长度。如下是二叉搜索树比较极端的一种情况,这使得二叉搜索树效率降低。而AVL树就是为了解决这一问题。   AVL树有哪些性质呢?首先它的左子树和有字数的高度差不超过1,并且它的左子树和右子树都要是AVL树才可以。 下面是AVL树的插入过程,其...

AVL树

AVL树的介绍 AVL树是根据它的发明者G.M. Adelson-Velsky和E.M. Landis命名的。 它是最先发明的自平衡二叉查找树,也被称为高度平衡树。相比于"二叉查找树",它的特点是:AVL树中任何节点的两个子树的高度最大差别为1。 (关于树的高度等基本概念,请参考"二叉查找树(一)之 图文解析 和 C语言的实现 "...

AVL树 Adelson-Velskii和Landis树:带有平衡条件的二叉查找树。平衡条件要容易保持,而且它须保证树的深度是O(logN)。最简单的想法是左右子树具有相同的高度。还有一种是要求每个结点都必须要有相同高度的左子树和右子树。一颗AVL树是其每个节点的左子树喝右子树的高度最多差一的二叉查找树。 在插入以后,只有那些从插入点到根节点的路径上的节点的平衡可能发生改变,我们上行到根可以找到一...
