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 retur...

旋转数组中的查找。[1, 2, 3, 4, 5, 6]的一个旋转数组为[4, 5, 6, 1, 2, 3]。在旋转数组中寻找一个数。
最直接的方法,一次遍历,时间复杂度O(n)。但是既然是一个部分有序的数组,那么对于有序的部分我们可以想方法用二分查找。这个效率可以提高。
