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...

python3 Binary search is a famous question in algorithm. For a given sorted array (ascending order) and a target number, find the first index of this number in O(log n) time complexity. If the target number does not exist in the array, return -1. ...
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.
If you recall, the binary search Python algorithm inspects the middle element of a bounded range in a sorted collection. But how is that middle element chosen exactly? Usually, you take the average of the lower and upper boundary to find the middle index: Python middle = (left + right)...
