(binary search trees) which form the basis of modern databases and immutable data structures. Binary search works very much the way humans intuitively search for a name in a yellow pages directory (if you have ever seen one) or the dictionary. In thi…

From: http://blog.jobbole.com/73517/ 二分检索是查找有序数组最简单然而最有效的算法之一.现在的问题是,更复杂的算法能不能做的更好?我们先看一下其他方法. 有些情况下,散列整个数据集是不可行的,或者要求既查找位置,又查找数据本身.这个时候,用哈希表就不能实现O(1)的运行时间了.但对有序数组, 采用分治法通常可以实现O(log(n))的最坏运行时间. 在下结论前,有一点值得注意,那就是可以从很多方面“击败”一个算法:所需的空间,所需的运行时间,对底层数据结构的访…

Binary Search: Search a sorted array by repeatedly  dividing the search interval in half. Begin with an interval covering the whole array. If the value of the search key is less than the item in the middle of the interval, narrow the interval to the…
Binary Search algorithm. Wikipedia definition: In computer science, binary search, also known as half-interval search, logarithmic search, or binary chop, is a search algorithm that finds the position of a target value within a sorted array. Binary s…
