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...

LeetCode:704_二分查找(Binary Search) 给定一个 n 个元素有序的(升序)整型数组 nums 和一个目标值 target ,写一个函数搜索 nums 中的 target,如果目标值存在返回下标,否则返回 -1。 示例1: 输入: nums = [-1,0,3,5,9,12], target = 9
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 = 1, r = maxn; while(l <= r) { int mid = (l + r) / ...
