Given two linked lists that represent two large positive numbers. The task is to subtract the given two numbers represented by the linked list. Subtract the smaller from the larger one.
Example 1:
Input:
L1 = 1->0->0
L2 = 1->2
Output: 8 8
Explanation: 12 subtracted from 100
gives us 88 as result.
Your Task:
The task is to complete the function subLinkedList() which should subtract the numbers represented by the linked list and return the head of the linked list representing the result.
Expected Time Complexity: O(N). Expected Auxiliary Space: O(N).
Constraints:
1 <= Length of the Linked List <= 10000

Avoid using static/global variables in your code as your code is tested
against multiple test cases and these tend to retain their previous values.
Passing the Sample/Custom Test cases does not guarantee the correctness of code.
On submission, your code is tested against multiple test cases consisting of all
possible corner cases and stress constraints.
