二叉搜索树(Binary Search Tree),又名二叉查找树、二叉排序树,是一种简单的二叉树。它的特点是每一个结点的左(右)子树各结点的元素一定小于(大于)该结点的元素。将该树用于查找时,由于二叉树的性质,查找操作的时间复杂度可以由线性降低到O(logN)。 当然,这一复杂

We already saw a recursion based implementation. But here, we are going to discuss how to implementwithout recursion using stackiteratively. When we are using recursion, what we are doing is traversing the left subtree always and then the current root and finally the right subtree. A...
However, there are also certain risks involved with recursion, which is one of the subjects of the next section.Covering Tricky Details Here’s what the author of The Art of Computer Programming has to say about implementing the binary search algorithm: “Although the basic idea of binary ...
The Cost of RecursionRecursive functions are often ideal for visualizing an algorithm, as they can often eloquently describe an algorithm in a few short lines of code. However, when iterating through a data structure's elements in practice, recursive functions are usually sub-optimal. Iterating ...

The base case of the recursion is reached when the LLIL_LOAD instruction of step 1 is encountered. The value of that LLIL_LOAD is the specified vtable pointer. The vtable pointer value is returned and propagates back through the previous iterations of the recursion to be used in those ...
A Binary Search Tree is a Binary Tree where every node's left child has a lower value, and every node's right child has a higher value. A clear advantage with Binary Search Trees is that operations like search, delete, and insert are fast and done without having to shift values in ...
