/*
    Write a function to delete a node (except the tail) in a singly linked list, given only access to that node.
    
    Link: https://leetcode.com/problems/delete-node-in-a-linked-list/

    Example: Supposed the linked list is 1 -> 2 -> 3 -> 4 and you are given the third node with value 3, the 
    linked list should become 1 -> 2 -> 4 after calling your function.

    Solution: None
