Solution: Find Minimum in Rotated Sorted Array II

Discover how to efficiently identify the minimum element in a rotated sorted array containing duplicates. This lesson explains a modified binary search approach that adjusts search boundaries based on comparisons, enabling you to handle duplicates and locate the minimum in logarithmic time in most cases. Understand the algorithm's process and complexity to apply it confidently in coding interviews.

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] ...
