Asked in company
Sam always likes to challenge Ninja with some problems. Today, he has come to Ninja for another challenge. Sam took a sorted array and rotated it clockwise by an unknown amount.
For example, he took a sorted array = [1, 2, 3, 4, 5] and if he rotates it by 2, then the array becomes: [4, 5, 1, 2, 3].
After rotating the sorted array, he asked Ninja Q queries, for each query Ninja has to search whether the number asked in that query is present in the rotated array or not, if the number is present then Ninja needs to tell Sam the index of the number, otherwise, he needs to tell Sam -1.
Since Ninja does not want to lose the challenge, he asked you to help him for the same. Your task is to find the index of the number asked in the query if it exists.
Problem approach
1. Iterate the array using the loop.
2. Check whether the given key present in the array i.e. arr[i] == key.
3. If yes,
print "Search Found".
4. Else
print "Search Not Found".

Asked in companies
Given a singly linked list of integers. Your task is to return the head of the reversed linked list.
For example:
The given linked list is 1 -> 2 -> 3 -> 4-> NULL. Then the reverse linked list is 4 -> 3 -> 2 -> 1 -> NULL and the head of the reversed linked list will be 4.
Follow Up :
Can you solve this problem in O(N) time and O(1) space complexity?
Problem approach
Initialize three pointers prev as NULL, curr as head, and next as NULL.
Iterate through the linked list. In a loop, do the following:
Before changing the next of curr, store the next node
next = curr -> next
Now update the next pointer of curr to the prev
curr -> next = prev
Update prev as curr and curr as next
prev = curr
curr = next
