Search In Rotated Sorted Array Problem Statement

Given a sorted array of distinct integers that has been rotated clockwise by an unknown amount, you need to search for a specified integer in the array. For each search query, you have to return the index of the element if found; otherwise, return -1.

Input:

The first line contains the size of the array, N.
The second line contains N space-separated integers representing the array elements A[i].
The third line contains the number of queries, Q.
The next Q lines each contain an integer, Q[i], which is the target value to search in the array.

Output:

For each query, output the index of the number if it is present in the array; otherwise, output -1. Each result should be printed on a new line.

Example:

Input:
N = 5
A = [4, 5, 1, 2, 3]
Q = 2
Q[0] = 1
Q[1] = 3
Output:
2
4
Explanation:

For the first query, the element 1 is found at index 2. For the second query, the element 3 is found at index 4.

Constraints:

  • 1 <= N <= 10^6
  • -10^9 <= A[i] <= 10^9
  • 1 <= Q <= 10^5
  • -10^9 <= Q[i] <= 10^9
  • Time complexity should be O(logN) for each query.
Note:

You do not need to handle the printing of the output. Just implement the search function to return the correct result.
