Analyze the snippet of code below. Identify the data structure used in this snippet of code, and explain what the method decipherMe() is computing.

2. Answer (Multiple Choice):
3. (_) The data structure that is used in this snippet of code is a stack. The method decipherMe() implements a PUSH operation.
4. (_) The data structure that is used in this snippet of code is a binary search tree. The method decipherMe() emulates a search to find out where in the binary search tree to insert a new node.
5. (_) The data structure that is used in this snippet of code is a singly linked list. The method decipherMe() logically removes from the singly linked list the node located immediately after the current node.
6. (_) The data structure that is used in this snippet of code is a singly linked list. The method decipherMe() inserts a new node into the singly linked list.

Explain your answer:

oublic void decipherMe(SomeNode currentNode, SomeNode newNode) \{ String currentName, newNodeKey; int strComparison; newNodeKey = newNode. key; currentKey = currentNode.key; strComparison = currentKey . compareToIgnoreCase ( newNodeKey ); if (strComparison == null) \{ currentNode.rightChild = newNode; newNode . parent = currentNode; \} else \{ decipherMe(currentNode.rightChild, newNode); \} \} else \{ if (currentNode.leftChild == null) \{ currentNode.leftChild = newNode; newNode . parent = currentNode; \} else \{ decipherMe(currentNode.leftChild, newNode); \} \}
