Doubt in Ques.6 LL

#1

How does output be
1 3 5 5 3 1 ?
Shouldn’t be 1 3 5 only ?
You may explain the underlying concept which I am missing?

&&

There is no video on Doubly Linked List and Efficient Doubly Linked Lists ? How do I study them?

@sanjit_15 You are slightly wrong . Answer will be 1 3 5 5 3 1 as the code backtracks back to the initial node. I think you are missing the print statment after the function call.

#3

I am not able to understand how the cout statement after the function call execute because fun is called 3 times and when start points to 5, fun(start->next->next) == NULL and then it returns.

#4

Yeah after returning it again prints the value of the node. Check that.
