Question	Topic	Difficulty
Target Value Search	Data Structures & Algorithms	Medium
Suppose an array sorted in ascending order is rotated at some pivot unknown to you beforehand. You are given a target value to search. If the value is in the array, then return its index; otherwise, return -1. Notes: Rotating an array at pivot $n$ gives you a new array that begins with the elements after position $n$ and ends with the elements up to position $n$ . You may assume no duplicate exists in the array. Bonus: Your algorithm’s runtime complexity should be in the order of $O(\log n)$ . Example: Input: `sample_input = [0,1,2,4,5,6,7] rotated_input = [4,5,6,7,0,1,2] target_value = 6` Output: `def target_value_search(rotated_input, target_value) -> 2` View Question Show Solution
