优化二,Interpolation+ Seq 插值检索的一个改进版本是,只要可推测我们猜测的元素位置是接近最终位置的,就开始执行顺序查找。 相比二分检索,插值检索的每次迭代计算代价都很高,因此在最后一步采用顺序查找,无需猜测元素位置的复杂计算,很容易就可以从很小的区域(大概10个元素)中找到最终的元素位置。 围绕插值检索的一大...

Binary Search is a searching algorithm for finding an element's position in a sorted array. In this tutorial, you will understand the working of binary search with working code in C, C++, Java, and Python.

Basically, binary search trees are fast at insert and lookup. The next section presents the code for these two algorithms. On average, a binary search tree algorithm can locate a node in an N node tree in order lg(N) time (log base 2). Therefore, binary search trees are good for "di...
The algorithm above can be implemented like this:Example Python: def search(node, target): if node is None: return None elif node.data == target: return node elif target < node.data: return search(node.left, target) else: return search(node.right, target) Run Example » ...
