Check if strings are rotations of each other or not
Basic Accuracy: 50.93% Submissions: 9044 Points: 1

Given two strings s1 and s2. The task is to check if s2 is a rotated version of the string s1. The characters in the strings are in lowercase.

 

Example 1:

Input:
geeksforgeeks
forgeeksgeeks
Output: 
1
Explanation: s1 is geeksforgeeks, s2 is
forgeeksgeeks. Clearly, s2 is a rotated
version of s1 as s2 can be obtained by
left-rotating s1 by 5 units.

 

Example 2:

Input:
mightandmagic
andmagicmigth
Output: 
0
Explanation: Here with any amount of
rotation s2 can't be obtained by s1.

 

Your Task:
The task is to complete the function areRotations() which checks if the two strings are rotations of each other. The function returns true if string 1 can be obtained by rotating string 2, else it returns false.

 

Expected Time Complexity: O(N).
Expected Space Complexity: O(N).
Note: N = |s1|.

 

Constraints:
1 <= |s1|, |s2| <= 107
