摘要： 题目：Follow up for "Search in Rotated Sorted Array":What ifduplicatesare allowed?Would this affect the run-time complexity? How and why?Write a function to determine if a given target is in the array.解题思路：该题与Search in Rotated Sorted Array的主要区别在于需要考虑A[low]与A[mid]相等、A[mid]与A[high]相等以及A[low]A[m 阅读全文

摘要： 题目：Suppose a sorted array is rotated at some pivot unknown to you beforehand.(i.e.,0 1 2 4 5 6 7might become4 5 6 7 0 1 2).You are given a target value to search. If found in the array return its index, otherwise return -1.You may assume no duplicate exists in the array.解题思路：数组的查找一般可以使用二分查找法，但是这道题里的 阅读全文
