// LEETCODE 154.Find Minimum in Rotated Sorted Array II { Hard } { Array }
// Suppose an array of length n sorted in ascending order is rotated between 1 and n times. For example, the array nums = [0,1,4,4,5,6,7] might become:
// [4,5,6,7,0,1,4] if it was rotated 4 times.
// [0,1,4,4,5,6,7] 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 that may contain duplicates, return the minimum element of this array.
// You must decrease the overall operation steps as much as possible.
// Example 1:
// Input: nums = [1,3,5]
// Output: 1
// Example 2:
// Input: nums = [2,2,2,0,1]
// Output: 0
// Constraints:
// n == nums.length
// 1 <= n <= 5000
// -5000 <= nums[i] <= 5000
// nums is sorted and rotated between 1 and n times.
### Solution
```
class Solution {
public int findMin(int[] nums) {
int left = 0;
int right = nums.length -1;
while (left < right)
{
int mid = left +(right - left)/2;
if(nums[mid] > nums[right])
left = mid+1;
else if(nums[mid] < nums[right])
right = mid;
else
right--;
}
return nums[left];
}
}
```
