Given two singly linked lists, find the Longest common suffix of two linked lists. If there are no common characters which are suffixes, return the minimum length of the two linked lists.
Input : list1 = w -> a -> l -> k -> i -> n -> g list2 = l -> i -> s -> t -> e -> n -> i -> n -> g Output :i -> n -> g Input : list1 = p -> a -> r -> t -> y list2 = p -> a -> r -> t -> y -> i -> n -> g Output :p -> a -> r -> t -> y
A simple solution is to use auxiliary arrays to store linked lists. Then print longest commons suffix of two arrays.
The above solution requires extra space. We can save space by first doing reverse of both linked lists. After reversing, we can easily find length of longest common prefix. Reversing again to get the original lists back.
One important point here is, order of elements. We need to print nodes from n-th to end. We use the above found count and print nodes in required order using two pointer approach.
