Hey @cbcao263, What does your len() function do?

#3

it’s for length.
lenght of ll

#4

I want you to send me your entire code consisting all your functions

#5


This is the whole code with all the functions that are insertAtHead,insertAtTail and length function and then I have inserted the elements into the stack and a queue and then I pop one element from queue and one element from stack as stack has a property LIFO.
So It will gonna arrange the elements in that way.
I am also making a new list and inserting there

Now I understood my mistake and I was pushing back at my original head that’s why it was giving the error
But then I removed the head2 and made head=NULL and inserting into head only and then it was giving o/p as 1234
Idk why :confused:

Corrected Code: -

So is it working fine now?

#7

Nope, Again giving some errors.
