(in C PROGRAMMING LANGUAGE)

1. Assume listl and list2 are two linked lists where list1 contains the values (1, 2, 3, 4) and list2 contains the values (5, 6, 7, 8). What would the values be in each list after the call to the function below? What operation does the function below do? void mystery (NodePtr 1istl, NodePtr 1ist2) NULL) if (*list! 1ist11ist2 while (current->next != NULL){ current-current-next; current-next1ist2 2. Write a function that takes an integer number n and returns a linked list of integers in descending order, from n down to 1. Each node should contain only one integer value o delete all even numbers from the list
