Hard-题目10:33. Search in Rotated Sorted Array

题目原文:
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 return -1.
题目大意:
对一个移位过的,无重复数字的数组,寻找目标数字并返回其下标。如果没有则返回-1.
题目分析:
一开始想到的思路是找到跳变点(即移动点),然后两边都是有序的,再二分查找,但是想不到logn复杂度的,就决定直接无脑找了。
源码:(language:java)

public class Solution {
    public int search(int[] nums, int target) {
        for(int i = 0;i<nums.length;i++)
            if(nums[i]==target)
                return i;
        return -1;
    }
}
