Solution:

# T:O(lgn)~O(n) S:O(1)
class Solution:
    # @param num, a list of integer
    # @return an integer
    def findMin(self, num):
        low, high = 0, len(num)
           
        while low < high - 1 and num[low] >= num[high - 1]:
            mid = low + (high - low) / 2
                
            if num[mid] > num[low]:
                low = mid + 1
            elif num[mid] < num[low]:
                if mid == high - 1:
                    return num[mid]
                else:
                    high = mid + 1
            else:
                low += 1

        return num[low]
