Find Minimum in Rotated Sorted Array
Given a rotated sorted array of unique integers Return the minimum element in O(log n) time Example: nums = [3,4,5,1,2] => 1 The array was originally [1,2,3,4,5] and rotated 3 times
This one is really a boundary-finding problem, even if it doesn't look like it at first. Interviewers love it because it reveals your boundary precision and your edge-case discipline. The trap is boundary drift—one wrong low/high update can loop forever or skip the answer.
