# Find Minimum In Rotated Sorted Array II Problem

## Description

LeetCode Problem 154.

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, a, a, …, a[n-1]] 1 time results in the array [a[n-1], a, a, a, …, 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:

``````1
2
Input: nums = [1,3,5]
Output: 1
``````

Example 2:

``````1
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.

int findMin(vector<int> &num) {
int l = 0,r = num.size() - 1,mid = 0;
while(l < r) {
mid = l + (r - l) / 2;
if (num[mid] > num[r]) l = mid + 1;
else if (num[mid] < num[r]) r = mid;
else r--;
}
return num[l];
}
