Question $1$

Assuming that the LinkedList class is a standard implementation of a Linked List of ListNode objects, what is the output from the

following code?

class ListNode:

def $($self$,$ data, next $=$ None$)$:

self.data$\backslash$cdot$=$ data

self.next $=$ next

L $=$ LinkedList$()$

L$.$addfirst$(1)$

L$.$addlast$(2)$

L$.$addfirst$(3)$

L$.$addfirst$(4)$

L$.$addlast$(5)$

for i in range$(3)$:

print$($L$.\_$head.next.data$)$

$3,1,2$

$3,3,3$

$3,1,2,5$
