Even though the array is rotated, at least half of it is sorted at any point. When you compute mid: - Either [left, mid] is sorted, or [mid, right] is sorted - Check if target is in the sorted half - If yes, search that half. If no, search the other half. This lets you eliminate half the array each time.
