Python implementation

class :
    def rotateString(self, A, B):
        """
        :type A: str
        :type B: str
        :rtype: bool
        """
        return len(A) == len(B) and A in B+B

Java implementation

class  {
    public boolean rotateString(String A, String B) {
        return A.length() == B.length() && (B+B).contains(A);
    }
}

Time complexity

O(N^2).
