Create a user-defined function called duplicates. This function will check to see if a singly linked list contains nodes with the same data stored. If any duplicates are found, return the value 1. Otherwise return 0. You may use the following typedef structure. typedef struct node_s{ int data; struct node_s * nextptr; }node_t;
