Binary search on rotated array
WebNot very elegant, but of the top off my head - just use binary search to find the pivot of the rotated array, and then perform binary search again, compensating for the offset of the pivot. Kind of silly to perform two full searches, but it does fulfill the condition, since O(log n) + O(log n) == O(log n). Keep it simple and stupid(tm)! WebJan 15, 2024 · By looking at the range of a sub-array, we know two things: we know, one, whether there was a rotation in that subarray or not; and, two, we know what the range of possible values are. So basically what we end up in this case is that our left subarray X has to be greater than five or X has to be less than two. And our right subarray, the values ...
