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.

数组中存在重复元素,处理方法与上一道题Search in Rotated Sorted Array一样,对边缘移动一步,直到边缘和中间不在相等或者相遇,这就导致了会有不能切去一半的可能。所以最坏情况(比如全部都是一个元素,或者只有一个元素不同于其他元素,而他就在最后一个)就会出现每次移动一步,总共是n步,算法的时间复杂度变成O(n...
LintCode Search For a Range (Binary Search) Binary Search模板: mid 和 target 指针比较,left/ right 和 target 比较。 循环终止条件: 最后剩两数比较(while(left + 1 < right))。 循环结束后根据要求检查最后两个数(left/ right 和 target 比较)。 publicclassSolution {/***@paramA : an integer sor...
The simplest solution would be to check every element one by one and compare it with k (a so-called linear search). This approach works in O(n) , but doesn't utilize the fact that the array is sorted.Binary search of the value 7 in an array. The...

A similar idea can be applied to binary search variations. For example, the following code counts how many times the key appears in the array. After the search, [p+1..q] is the range with value k. intcount(intx[],intn,intk){intp=-1,q=-1;for(inta=n;a>=1;a/=2){while(p+...
Only if monotonousness is known, binary search can be performed. Otherwise, binary search cannot be performed since the half part cannot be considered useless. Part B— Implementation Here we give out a standard code below: bool chk(int x) { //something } signed main() { //... l = ...

lintcode:Binary Search 二分查找 题目: 二分查找 给定一个排序的整数数组(升序)和一个要查找的整数target,用O(logn)的时间查找到target第一次出现的下标(从0开始),如果target不存在于数组中,返回-1。 样例 在数组[1, 2, 3, 3, 4, 5, 10]中二分查找3,返回2。
