Search in Rotated Sorted Array Suppose a sorted array is rotated at some pivot unknown to you beforehand. (i.e., 0 1 2 4 5 6 7 might become 4 5 6 7 0 1 2). You are given a target value to search. If found in the array return its index, otherwise retu…

Follow up for "Search in Rotated Sorted Array":What if duplicates are allowed? Would this affect the run-time complexity? How and why? Write a function to determine if a given target is in the array. 这个和前面的一个不一样就在于可能会有重复的数字,那么判断的时候就应该注意了,遇到start…

题目描述: python实现 Search in Rotated Sorted Array 搜索旋转排序数组   中文:假设按照升序排序的数组在预先未知的某个点上进行了旋转. ( 例如,数组 [0,1,2,4,5,6,7] 可能变为 [4,5,6,7,0,1,2] ). 搜索一个给定的目标值,如果数组中存在这个目标值,则返回它的索引,否则返回 -1 . 你可以假设数组中不存在重复的元素. 你的算法时间复杂度必须是 O(log n) 级别. 英文:Suppose an array sorted i…

11.3 Given a sorted array of n integers that has been rotated an unknown number of times, write code to find an element in the array. You may assume that the array was originally sorted in increasing order. EXAMPLE Input: find 5 in {15, 16, 19, 20, 2…
