Write a function

ListNode *removeFirst(ListNode *ptr)

Write a function that changes the places of the first and second nodes of a linked list. I.e. the First node will become the second node, and the second node will become the first node. THE FUNCTION WILL NOT EXCHANGE DATA, IT WILL CHANGE LINKS.
Write a void function that takes a linked list of integers and removes all the duplicate elements from the list. The function will have one call-by-reference parameter that is a pointer to the head of the list. After the function is called, this pointer will point to the head of a linked list that has the nodes that have all the distinct integers. Place your function in a suitable test program.
