//! Suppose an array sorted in ascending order is rotated at some pivot unknown to you beforehand.
//!
//! (i.e., [0,1,2,4,5,6,7] might become [4,5,6,7,0,1,2]).
//!
//! Find the minimum element.
//!
//! The array may contain duplicates.
//!
//! ```
//! Example 1:
//!
//! Input: [1,3,5]
//! Output: 1
//! ```
//!
//! ```
//! Example 2:
//!
//! Input: [2,2,2,0,1]
//! Output: 0
//! ```
//!
//! Note:
//!
//! This is a follow up problem to Find Minimum in Rotated Sorted Array.
//! Would allow duplicates affect the run-time complexity? How and why?
//!
