	# Problem Statement
	> 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.    Follow up: This problem is similar to Find Minimum in Rotated Sorted Array, but nums may contain duplicates. Would this affect the runtime complexity? How and why?   

	# Explanation
	*   **Binary Search with Handling Duplicates:** Employ binary search to efficiently narrow down the search space. The key is to handle duplicate elements effectively, as they can disrupt the standard binary search logic. If `nums[mid] == nums[left]`, increment `left` to shrink the search space.
*   **Identify Sorted Subarrays:** In each iteration, determine whether the left or right subarray is sorted. If the left part is sorted, the minimum element must be in the right part, and vice-versa.
*   **Update Search Space:** Based on the sorted subarrays, adjust the `left` and `right` pointers to continue the binary search in the appropriate direction, ensuring that the minimum element is always within the search space.

*   **Runtime Complexity:** O(log n) in the average case, O(n) in the worst case (when most elements are duplicates). **Storage Complexity:** O(1).

	
	# Code
	```python
	def findMin(nums):
    """
    Finds the minimum element in a rotated sorted array that may contain duplicates.

    Args:
        nums: A list of integers representing the rotated sorted array.

    Returns:
        The minimum element in the array.

    left, right = 0, len(nums) - 1

    while left < right:
        mid = (left + right) // 2

        if nums[mid] > nums[right]:
            left = mid + 1
        elif nums[mid] < nums[right]:
            right = mid
        else:
            # Handle duplicate case: nums[mid] == nums[right]
            right -= 1

    return nums[left]
