The figure below illustrates a sentinel list with two elements, "foo" and "bar". The head node has a special value, "_HEAD__. The sentinel node at the end has a special value, "_SENTINEL_.". Note that there are double underscores at the beginning and end of the special values. An empty SentinelList has only the head connected to the sentinel, with the sentinel connected to null. The two special nodes are never removed and always anchor the two ends of the list. Having sentinels can be a big help in coding linked lists. They simplify adding and removing. Your Task You are given a class Node that implements a node in the linked list. Values are Strings. Your task is to implement the SentinelList class with these methods: - public sentinellist() - Create an empty sentinel list. The empty sentinel list of size 0 has two special nodes, a head with value "_HEAD__ and a sentinel at the end with value "_SENTINEL_". - public Node getHead() - Return the special head node. - public Node getsentinel() - Return the special sentinel node. - public int size() - Return the number of elements in the sentinel list. - public void addFront(String value) -- Add the value to the front of the list - public boolean lookup(String value) - Return true if the value was found at least once in the list, or false otherwise. - public void addBack(String value) - Add the value to the end of the list - public boolean remove(String value) - Remove the .
