Hello all.
I need a function that produces this strings
a , b, aa ,ab, ba ,bb ,aaa,aab, aba ,abb baa ,bab ,bba , bbb ,aaaa...
It 's NOT exactly like binary counting (in binary after bbb (111) is aaaa (1000))
char* GetNextString(char* previous)
i.e . GetNextString("bba")="bbb" , GetNextString("bbb")="aaaa"
I hope you understand what i need
Thank you !
