Dynamic Planning-optimal binary search tree

Problem description Given a sequence K = {K1, K2,..., composed of n different keywords ,..., kN}, and the keywords are ordered. For each key word Ki, the probability of one search for Ki is pi. Some search values may not be in K, so there are n + 1 virtual keys D0, D1,..., DN represents a value no longer in K. D0 indicates all values smaller than K1, and DN indicates all values greater than kn. for I =,...,

Algorithm Learning Search (order, dichotomy, sort binary tree, and Hash table)

;>1);if(value==Array[Middle]) return middle;Else if(value>Array[Middle]) {start = middle +1; }Else{End= Middle-1; }} Return-1;}Analysis:As we said above, the complexity of the common data lookup algorithm is O (n). The binary lookup algorithm has an O (log (n)) complexity.This method is at least 1 times, so how many times does it take? We found that a maximum of log2n+1 needed to be log2n down, plus 1. We can find an example to figure out, for example
