to the first node of each of the lists to be merged and should return

C programming assignment, 1. Write a program that concatenates two linked lists of characters. The program should include function concatenate that takes pointers to both lists as arguments and concatenates the second list to the first list. 2. Write a program that merges two ordered lists of integers into a single ordered list of integers. Function merge should receive pointers to the first node of each of the lists to be merged and should return a pointer to the first node of the merged list. 3. Write a program that creates a linked list of 10 characters, and then creates a copy of the list in reverse order.
