153. Find Minimum in Rotated Sorted Array

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).

Find the minimum element.

代码如下：

 public class Solution {
     public int findMin(int[] nums) {
         Arrays.sort(nums);
         return nums[0];
     }
 }
