Coding Recipies: Rotated Strings


Check if the given strings are rotated form of each other.
The approach is to check if the strings are of same length, then check if s2 is sub-string of s1 concatenated with itself.
public static boolean isRotated(String s1,String s2){
  return s1.length()==s2.length() && (s1+s1).indexOf(s2)!=-1 ;
 }
