get the size of both the linked list say d1,d2 ; get their diff like df=abs(d1-d2);
now take 2 pointers both poiting to the start of both the linked list . go to bigger list now move this pointer until both the distance becomes equal . at this point we have one pointer from smaller list pointing to the start of the list and another pointer in bigger list pointing to node where distance came equal , move these 2 pointers until both point to the same node .. and we are done .
