Find Minimum in Rotated Sorted Array
Suppose an array sorted in ascending order is rotated at some pivot unknown to you beforehand. [#153]
(i.e., [0,1,2,4,5,6,7] might become [4,5,6,7,0,1,2] ).
Find the minimum element.
You may assume no duplicate exists in the array.
Examples:
Input: [3,4,5,1,2]
Output: 1
Input: [4,5,6,7,0,1,2]
Output: 0
