This challenge is part of a tutorial track by MyCodeSchool
You’re given the pointer to the head nodes of two linked lists. Compare the data in the nodes of the linked lists to check if they are equal. If all data attributes are equal and the lists are the same length, return . Otherwise, return .
Example
The two lists have equal data attributes for the first nodes. is longer, though, so the lists are not equal. Return .
Function Description
Complete the compare_lists function in the editor below.
compare_lists has the following parameters:
- SinglyLinkedListNode llist1: a reference to the head of a list
- SinglyLinkedListNode llist2: a reference to the head of a list
Returns
- int: return 1 if the lists are equal, or 0 otherwise
Input Format
The first line contains an integer , the number of test cases.
Each of the test cases has the following format:
The first line contains an integer , the number of nodes in the first linked list.
Each of the next lines contains an integer, each a value for a data attribute.
The next line contains an integer , the number of nodes in the second linked list.
Each of the next lines contains an integer, each a value for a data attribute.
Constraints
Output Format
Compare the two linked lists and return 1 if the lists are equal. Otherwise, return 0. Do NOT print anything to stdout/console.
The output is handled by the code in the editor and it is as follows:
For each test case, in a new line, print if the two lists are equal, else print .

Explanation
There are test cases, each with a pair of linked lists.
In the first case, linked lists are: 1 -> 2 -> NULL and 1 -> NULL
In the second case, linked lists are: 1 -> 2 -> NULL and 1 -> 2 -> NULL
