Linked list(quiz)

#1

8th question.Can you clarify how can a 1 pointer in each node help in traversing back and forth?

#2

@bommareddyjyothiswaroopreddy,
Which qn are you talking about? I think that problem is considering a doubly linked list, so we can iterate in either direction.

#3

the question was…
how can you make a double linked list memory efficient?

#4

@bommareddyjyothiswaroopreddy,
So, yeah in a double linked list you can traverse back and forth.
