 Find Minimum in Rotated Sorted Array – LeetCode Solution Java , Python 3, Python 2 , C , C++, Best and Optimal Solutions , All you need.

Suppose an array of length n sorted in ascending order is rotated between 1 and n times. For example, the array nums = [0,1,2,4,5,6,7] might become:

  • [4,5,6,7,0,1,2] if it was rotated 4 times.
  • [0,1,2,4,5,6,7] 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 of unique elements, return the minimum element of this array.

You must write an algorithm that runs in O(log n) time.

 

Example 1:

Input: nums = [3,4,5,1,2]
Output: 1
Explanation: The original array was [1,2,3,4,5] rotated 3 times.

Example 2:

Input: nums = [4,5,6,7,0,1,2]
Output: 0
Explanation: The original array was [0,1,2,4,5,6,7] and it was rotated 4 times.

Example 3:

Input: nums = [11,13,15,17]
Output: 11
Explanation: The original array was [11,13,15,17] and it was rotated 4 times. 

 

Constraints:

  • n == nums.length
  • 1 <= n <= 5000
  • -5000 <= nums[i] <= 5000
  • All the integers of nums are unique.
  • nums is sorted and rotated between 1 and n times.

        if (num.length == 1) {
            return num[0];
        }
        int start = 0, end = num.length - 1;
        while (start < end) {
            int mid = (start + end) / 2;
            if (mid > 0 && num[mid] < num[mid - 1]) {
                return num[mid];
            }
            if (num[start] <= num[mid] && num[mid] > num[end]) {
                start = mid + 1;
            } else {
                end = mid - 1;

class Solution:
    def findMin(self, nums: List[int]) -> int:
        if len(nums) == 1 or nums[0] < nums[-1]:

        left, right = 0, len(nums) - 1
        while left <= right:
            mid = left + (right - left) // 2
            if mid > 0 and nums[mid - 1] > nums[mid]:  # The nums[mid] is the minimum number
                return nums[mid]
            if nums[mid] > nums[right]:  # search on the right side, because smaller elements are in the right side
                left = mid + 1
            else:
                right = mid - 1  # search the minimum in the left side
