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.
