Solution: Find Minimum in Rotated Sorted Array II

Understand how to locate the minimum element in a rotated sorted array that may contain duplicates by using a modified binary search. Explore the approach of adjusting search boundaries based on comparisons, handling edge cases with duplicates, and optimizing for time and space efficiency. This lesson equips you to implement and reason about this common algorithmic problem.

Statement

Imagine you have an array, nums, of length nn that was originally sorted in non-decreasing (ascending) order. This array has been rotated between 11 and nn times. For example, the sorted array [0,2,3,3,5,7,11][0,2,3,3,5,7,11] can become:

  • [5,7,11,0,2,3,3][5,7,11,0,2,3,3] ...
