Find Minimum in Rotated Sorted Array

In this tutorial, I am going to discuss a very interesting problem find minimum in rotated sorted array.

Given an array which is sorted in ascending order is rotated at some unknown point. Write a code to find the minimum element in a sorted and rotated array.

You may assume no duplicate exists in the array.

For example:

Example 1:

Input: [6, 7, 8, 1, 2]
Output: 1

The minimum element in this sorted and rotated array is 1.

Example 2:

Input: [8, 9, 10, 1, 0, 1, 2]
Output: 0

In this example, the minimum element is 0.
