Notes: https://github.com/team-codebug/babua... Master two important rotated sorted array problems with duplicates using binary search. In this video, we solve: 81. Search in Rotated Sorted Array II 154. Find Minimum in Rotated Sorted Array II Both problems are slightly trickier than their original versions because the array can contain duplicate values. Duplicates create confusion in binary search because sometimes we cannot clearly decide which half is sorted. For example: [1, 0, 1, 1, 1] Here, nums[low], nums[mid], and nums[high] can all be equal, making it difficult to know whether the left half or right half is sorted. In this video, we cover: What changes when duplicates are allowed Why normal rotated binary search is not always enough How duplicate values create ambiguity The role of low, mid, and high How to safely shrink the search space Detailed dry run for Search in Rotated Sorted Array II Detailed dry run for Find Minimum in Rotated Sorted Array II Java code explanation Time and space complexity Why the worst-case time complexity can become O(n) For Search in Rotated Sorted Array II, we learn how to handle the confusing case: if (nums[low] == nums[mid] && nums[mid] == nums[high]) { low++; high--; } For Find Minimum in Rotated Sorted Array II, we learn why this condition is useful: if (nums[mid] greater than nums[high]) { low = mid + 1; } else if (nums[mid] less than nums[high]) { high = mid; } else { high--; } These two problems are perfect for understanding how binary search changes when duplicate values are present. This video is useful for anyone preparing for coding interviews, LeetCode practice, DSA patterns, and mastering modified binary search problems.
