i think we just construct a string C that repeate string A twice, for example, string A is 'abcd', and string C is 'abcdabcd', then check whether string B is a substring of string C.
by the way, the string C can be saved by utilizing string A and modular function, for example, the char at position i in string C is exactly the char at i%len(A) in string A. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
