Problem: Search In Rotated Sorted Array
Given a sorted array that has been rotated clockwise by an unknown amount, you need to answer Q
queries. Each query is represented by an integer Q[i]
, and you must determine if this integer exists in the rotated array. Return the index if found, otherwise return -1.
Input:
The first line contains an integer N
, representing the size of the array.
The second line contains N
space-separated integers, representing the elements of the array A
.
The third line contains an integer Q
, representing the number of queries.
The next Q
lines each contain a single integer Q[i]
, the number to search for in the array.
Output:
For each query, output the index of the number if found; otherwise, output -1. Each output should be on a new line.
Example:
Input:
N = 5
A = [4, 5, 6, 7, 0, 1, 2]
Q = 3
Q[i] = [0, 3, 6]
Output:
4
-1
2
Constraints:
1 ≤ N ≤ 10^6
-10^9 ≤ A[i] ≤ 10^9
1 ≤ Q ≤ 500
-10^9 ≤ Q[i] ≤ 10^9
- Time Limit: 1 sec
Note:
The problem requires solving each query in O(logN) time complexity.

This is a problem where a sorted array is rotated and we need to search for given numbers in the array.
The array is rotated clockwise by an unknown amount.
We need to perform binary search to find the ...read more
