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
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 = ...
Given an array of integers nums which is sorted in ascending order, and an integer target, write a function to search target in nums. If target exists, then return its index. Otherwise, return -1.You must write an algorithm with O(log n) runtime complexity. 英文版地址 leetcode.com/prob...
