Language/Type:
C++ linked lists pointers
Write the code that will produce the given "after" result from the given "before" starting point by modifying
links between the nodes shown and/or creating new nodes as needed. Assume that the nodes have already
been declared and initialized to match the "before" figure below. There may be more than one way to write
the code, but do NOT change any existing node's data field value.
If a variable does not appear in the "after" picture, it doesn't matter what value it has after the changes are
made. If a given node object does not appear in the "After" picture, you must free its memory to avoid a
memory leak.
Before list: 1 -> 2/
After list: 3 > 1 -> 2/
Assume that you are using the following ListNode structure:
struct ListNode {
int data;
// data stored in this node
ListNode* next; // a link to the next node in the list
ListNode (int data = Ø, ListNode* next = nullptr) {...} // constructor
};
