首先可以想到逐步移位,但是这种方法显然太浪费时间,不可取。下面介绍利器『三步翻转法』,以[4, 5, 1, 2, 3]为例。 由以上3个步骤可知其核心为『翻转』的in-place实现。使用两个指针,一个指头,一个指尾,使用for循环移位交换即可 JAVA: C++: 源码分析 首先找到分割点,随后分 ...

153. Find Minimum in Rotated Sorted Array 二分题目,由于rotated存在,a[mid]<key不能判断在哪一边搜索。 可以根据a[low]与a[high]的关系,来判断哪一边有序,哪一边存在rotate,进而缩小搜索区间。 开区间写法:(由于搜索区间和解区 ...

这道题目很经典,本人表示在面试时遇见过,要求复杂度为O(logn),很显然必须用二分查找,但是旋转导致数组并非从左到右都是有序的,因此我们在查找时需要做判断,我们找打的终点左边或者右边至少一边是有序的;如果中间数小于最右边的数字,则右半段是有序的;如果中间数字大于最右边数字,则左半段是有序的,参考下 ...
