Write a C program to declare a node struct with 2 member variables: integer data and a pointer next which reference to another node

1. Create a singly linked list sorted in increasing order that contains n nodes (n input from keyboard), each node get random data within the range [-1010]

2. Write a function to output a given linked list

3. Break a given list into 2 separate lists: one contains all negative integers, and the other contains positive integers (include 0)

4. Find the integer values that have the highest occurrences in the list

5. Remove all duplicates from the list
