Cоnsider the fоllоwing clаss. public clаss LinkedNode { protected String dаta; protected LinkedNode next; public LinkedNode(String data, LinkedNode next) { this.data = data; this.next = next; } public static LinkedNode someMethod(LinkedNode head) { LinkedNode previous = null; LinkedNode current = head; LinkedNode next = null; while (current != null) { next = current.next; current.next = previous; previous = current; current = next; } head = previous; return head; } } What does someMethod defined in the above LinkedNode class do?
