Suppose an array of length n sorted in ascending order is rotated between 1 and n times. For example, the array nums = [0,1,2,4,5,6,7] might become:
[4,5,6,7,0,1,2] if it was rotated 4 times.
[0,1,2,4,5,6,7] if it was rotated 7 times.
Notice that rotating an array [a[0], a[1], a[2], ..., a[n-1]] 1 time results in the array [a[n-1], a[0], a[1], a[2], ..., a[n-2]] .
Given the sorted rotated array nums of unique elements, return the minimum element of this array .
You must write an algorithm that runs in O(log n) time .
n == nums.length1 <= n <= 5000-5000 <= nums[i] <= 5000All the integers of nums are unique .nums is sorted and rotated between 1 and n times.
