33. Search in Rotated Sorted Array
一、题目 1、描述 2、题意 在一个有序但可能经过左右移动的数组里求出目标数的下标! 二、解答 1、思路: 可以采用依次比较的方法 2、优化: 因为移动后,一定有一个数字是最大的且该数将数组分成左右两边,左边的每一个数都比右边大,或者右边的数都比左边大!所以可以找出中间数,然后采用两次二分查找即可! ...

Find Minimum in Rotated Sorted Array -- LeetCode
这道题是Search in Rotated Sorted Array的扩展,差别就是如今不是找一个目标值了,而是在bst中找最小的元素。主要思路还是跟Search in Rotated Sorted Array差点儿相同。还是通过左边界和中间的大小关系来得到左边或者右边有序的信息。假设左半边有序。那 ...
